David, can you please tell me at what point you see the failure?
Parallel builds are working fine for me on x86_64 (make -j, make -j 4),
so I suspect that there is something in your configure or build options
that I am missing. My configure:

../glibc/configure --prefix=$HOME/sandbox/glibc-sandbox

There is a $(before-compile) variable that has dependencies to be added
for most object files, so I'd like to know which one failed for you. I
checked out the dependencies in *.d and *.dt for the required sources
(framestate.c, unwind-forcedunwind.c and rt-unwind-resume.c) and all of
them have $(objpfx)/gnu/lib-names.h as a dependency and hence should
not build before lib-names.h is generated. Can you tell me what
configure/build options you're using and for which arch?

Thanks,
Siddhesh
