I build for an i386 target on an x86_64 Fedora system using CFLAGS=-m32. 
  It built successfully and even seems to work, but musl-gcc ends up 
omitting -m32 in the link stage, so it tries to pick up the wrong 
libraries and fails to link.

ISTM either musl-gcc should accept and honor -m32 (and work!) or 
musl-gcc should hardcode the target architecture (i.e. musl-gcc should 
target i386 even without -m32).
