Hmm, okay, and that failure is during the gcc stage.

Seem unlikely, but possible.  Looking at the environment settings is
probably a good idea.

Have you installed any compiler wrappers, e.g. ccache, or hardening
wrappers?

You could also take this command:

depbase=`echo as.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`; gcc -DHAVE_CONFIG_H -I. -I/home/noah/programs/opensource/glibc-dev/build-many/src/binutils/gas  -I. -I/home/noah/programs/opensource/glibc-dev/build-many/src/binutils/gas -I../bfd -I/home/noah/programs/opensource/glibc-dev/build-many/src/binutils/gas/config -I/home/noah/programs/opensource/glibc-dev/build-many/src/binutils/gas/../include -I/home/noah/programs/opensource/glibc-dev/build-many/src/binutils/gas/.. -I/home/noah/programs/opensource/glibc-dev/build-many/src/binutils/gas/../bfd -DLOCALEDIR="\"/home/noah/programs/opensource/glibc-dev/build-many/install/compilers/x86_64-linux-gnu/share/locale\""  -W -Wall -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wstack-usage=262144 -Werror -Wwrite-strings -I/home/noah/programs/opensource/glibc-dev/build-many/src/binutils/gas/../zlib -g -O2     -MT as.o -MD -MP -MF $depbase.Tpo -c -o as.o /home/noah/programs/opensource/glibc-dev/build-many/src/binutils/gas/as.c

add --save-temps, and invoke it in the directory
/home/noah/programs/opensource/glibc-dev/build-many/build/compilers/x86_64-linux-gnu/binutils/gas.
This should produce an as.i file, and from the # lines in it, it should
be possible to glean from where the config.h file actually used comes
from.  Or perhaps use the -H option and hope that the include nesting
reveals what's going on.

Thanks,
Florian
