No, this was a bug in the code.  I think all you needed to do was to
really clean in libc and ld.elf_so, but a full build should certainly
be ok.  The problem was makefile flags, and there aren't dependencies
for every object on every makefile that influences flags in any way.
Perhaps there should be, but it would be painful.  Very likely what
happened is that you rebuilt libc with the bad src/lib/libc/Makefile
and then after it got fixed libc didn't get rebuilt.
