# 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.

# NASTY HACK #
# 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.

# Install a symlink for the program interpreter (ld.so) so that binaries
# built in stage 3 before the stage 3 glibc is built can use it.
#
# The name of the dynamic loader is hardcoded in GCC during its 'configure'
# stage, but the file is actually provided by the libc (usually GLIBC). It
# would be better if we could ask GCC or GLIBC what the expected name of the
# ld.so is for the given platform rather than figuring it out
