There are various ways of overcoming the circular dependency between
glibc and gcc.  Probably the best one with current glibc sources is
to configure glibc and run "make install-headers" before building
gcc.  Last time I checked, this didn't quite work, and I found I needed
to create a dummy gnu/stubs.h.  Bootstrapping tools from scratch is
still a pain..

It would exist if you had installed the required headers there. :)
