# Fix up GCC to handle the sysroot containing eglibc 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.
