[Bug bootstrap/28102] New: GNU Hurd bootstrap error: 'OPTION_GLIBC' undeclared

["tbm at cyrius dot com" <gcc-bugzilla at gcc dot gnu dot org>]

GCC 4.2 on GNU Hurd currently fails to bootstrap with the following error:

This is probably due to the patch from

The glibc dynamic linker on GNU is /lib/ld.so.1

I tried to define GLIBC_DYNAMIC_LINKER in gcc/config/gnu.h but it seems that's
not the right fix.
