It's not finding crtbegin.o when I do that, and the fact that (according to strace), gcc thinks: access("/usr/x86_64-unknown-linux/bin/../lib/gcc/x86_64-unknown-linux/4.2.1/../../../../lib64/crtbegin.o", R_OK) = -1 ENOENT (No such file or directory) Is a good place to look for it is one of the REASONS I wrote a wrapper that goes "--nostdinc --nostdlib" and then starts again. ("I say we take off and nuke the entire site from orbit. Only way to be sure.") However, it sounds like you're using a stale version of the aboriginal build environment because I upgraded to a binutils that can build musl (and yes actually tested it at one point) several months ago...
