Update build options --nostdlib --nolibc --emit-stdlib --forcelinker … (#999)

Browse Source 
Update build options --nostdlib --nolibc --emit-stdlib --forcelinker --strip-unused. Fix error with vectors in $foreach. Also error if a $foreach iterating over an empty list. Rename forcelinker -> system-linker
