Comment 1:

This is an issue with cmd/dist.
Currently the behavior is to append the other arguments in CC (["gcc"], in this case)
/after/ "-o xyz". At build.c:633
vadd(&link, gccargs.p[0]);
vadd(&link, "-o");
vadd(&link, bpathf(&b, "%s/%s%s", tooldir, name, exe));
vcopy(&link, gccargs.p+1, gccargs.len-1);http://golang.org/cl/5700044
I have a CL to change this at http://golang.org/cl/5700044, but it may break
some other wanted behavior. Perhaps we should pay attention to CFLAGS?

I am enjoying life without $CFLAGS.  Your CL is fine.
