# Fix up GCC to handle the sysroot containing glibc being in a different
# location for each chunk build.
#
# For headers, it's enough to pass -B in the CPPFLAGS. This would work for
# the startup files (crt*.o) as well, except where libtool is involved (in
# which case it strips -B out of your LDFLAGS before calling GCC). We get
# around this by making GCC locate them relative to the environment variable
# STAGE2_SYSROOT, which we can then set along with CPPFLAGS in each stage 2
# chunk build.
#
# We also force the use of the program loader at PREFIX/lib/ld.so instead
# of its usual home in /lib or /lib64, which is necessary for the output of
# stage 2 to work as a chroot when building stage 3.

# We create a symlink to the actual specs here, so that later the
# symlink can be replaced with a dangling link.
#
# This is necessary as we need to have gcc use its internal specs,
# which can differ to the specs generated by `gcc -dumpspecs`.
#
# The dangling symlink will not make it onto the final system, just
# like all other bootstrap only components.

# FIXME: get a better way of finding the name of the loader. The lib64
# path is hardcoded into glibc in the file
