# GCC module
# ----------
# Unfortunately, while gcc _should_ be a host module,
# libgcc is a target module, and gen* programs are
# build modules. So GCC is a sort of hybrid.
# gcc is the only module which uses GCC_FLAGS_TO_PASS.
# Don't use shared host config.cache, as it will confuse later
# directories; GCC wants slightly different values for some
# precious variables. *sigh*
# We must skip configuring if toplevel bootstrap is going.
