* fixes for RISC-V ABI Implementation #1567
Fixed RISC-V floating-point ABI by correcting the target triple to
`riscv64-unknown-linux-gnu`, adding the `target-abi` module flag, and
ensuring ABI-required CPU features are enabled.
I tested this with:
```bash
build/c3c compile-only --target linux-riscv64 rv_hello.c3
readelf -h obj/linux-riscv64/rv_hello.o | grep Flags
# Output: Flags: 0x5, RVC, double-float ABI
```
```bash
# and qemu because I don't have a riscv machine :/
qemu-riscv64-static -L /usr/riscv64-linux-gnu ./rv_hello
```

@lerno I purposedly left these two failing tests to clearly see the
difference.
`test/test_suite/abi/riscv64-lp64-lp64f-abi-1.c3t`
`test/test_suite/abi/riscv64-lp64-abi.c3t`
* improve Linux cross-compilation, specifically for RISC-V
- Implement automatic sysroot and CRT object discovery for RISC-V.
- Fix dynamic linker paths and emulation flags for LLD.
- Link against libgcc to resolve required arithmetic symbols.
* Update tests.
* fix linker CRT detection by centralizing host arch check
use target_host_arch() in linker.c
move target_host_arch() from hostinfo.c to target.c
* missing debug info

* Add NetBSD Support
Includes:
- Hints to find non-compatibility libc functions
- Struct and constant definitions for sockets, polling, etc.
- Changes to the linker code to work around some quirks in the NetBSD dynamic linker
- A target triple for netbsd aarch64 so llvm builds/links the compiler properly on this platform
* Updated releasenotes and some compacting

* added switch statement to link musl-based linux distros to ld-musl-x86-64.so.2
* Update linker.c
/lib/ld-musl-x86-64.so.1 is musl's ld so. My bad
* don't need ENV_MUSLEABI.* in the switch for x86_64
* typo
* Added a CI test for an Alpine Linux container
* Update main.yml
Forgot to have bundle_output job use `env.LLVM_RELEASE_VERSION_ALPINEv3_22`.
* Added env.LLVM_RELEASE_VERSION_ALPINEv3_22 to `upload artifacts`
* changed bundle name to c3-musl-${{matrix,build_type}}.tar.gz
* Undid an accidental name change in build-linux-ubuntu22
* Update main.yml
sudo doesn't exist in alpine by default, and runs in root by default.
* Update main.yml
* Update main.yml
* Update main.yml
* Update main.yml
`--linker=builtin` fails because it forces search of `/lib64/ld-linux-x86-64.so.2`. lib64 doesn't exist on musl unless created as a symlink, and the appropriate so is /lib/ld-musl-<arch>.so.1
* Update main.yml
* Update main.yml
* Update main.yml
* Update main.yml
make isn't in alpine by default. added it in for risc-v example.
* gcc-riscv-none-elf is alpine's package
* using realpath for c3c over using relative pathing
* Have to use relative path for arguments in compiler test
* added --linker=builtin to
* Added linux-musl-<arch> targets
* Added more ld targets for glibc
* set both testproject libs as folders until they behave better
* added linux-musl-x64 target to clib2
* added riscv targets for ld-linux
* ubuntu doesn't have ld in /lib, but solely in /lib64?
* Make MUSL distinct from the target.
* Fix default in project schema
* Fix define
* Fix manifests.
* Update main.yml
add --linux-libc flag for builtin linking
* Grammar refresh
* Update releasenotes.

* Update feature handling for Wasm, RiscV, Aarch64, Arm
* - The option `--riscvfloat` renamed `--riscv-abi`.
- Add initial `--cpu-features` allowing fine grained control over CPU features.
- Output llvm/asm into llvm/<platform> and asm/<platform> by default.
- Don't delete .o files not produced by the compiler.
- Correctly handle in/out when interacting with inout.
Upgrade of mingw in CI. Fix problems using reflection on interface types #1203. Improved debug information on defer. $foreach doesn't create an implicit syntactic scope.
Error if `@if` depends on `@if`. Updated Linux stacktrace. Fix of default argument stacktrace. Allow linking libraries directly by file path. Improve inlining warning messages. Added `index_of_char_from`. Compiler crash using enum nameof from different module #1205. Removed unused fields in find_msvc. Use vswhere to find msvc. Update tests for LLVM 19
0.5.5 Disallow multiple `_` in a row in digits, e.g. `1__000`. #1138. Fixed toposort example. Struct/union members now correctly rejects members without storage size #1147. `math::pow` will now correctly promote integer arguments. `math::pow` will now correctly promote integer arguments. Added `new_aligned` and `alloc_aligned` functions to prevent accidental under-alignment when allocating simd. Pointer difference would fail where alignment != size (structs etc) #1150. Add test that overalignment actually works for lists. Fixed array calculation for npot2 vectors. Use native aligned alloc on Windows and POSIX. Deprecates "offset". Simplification of the Allocator interface.
