# HACK: we need to override SHLIB_LC from gcc/config/t-slibgcc-elf-ver or
# gcc/config/t-libunwind so -lc is removed from the link for
# libgcc_s.so, as we do not have a target -lc yet.
# This is not as ugly as it appears to be ;-) All symbols get resolved
# during the glibc build, and we provide a proper libgcc_s.so for the
# cross toolchain during the final gcc build.
#
# As we cannot modify the source tree, nor override SHLIB_LC itself
# during configure or make, we have to edit the resultant
# gcc/libgcc.mk itself to remove -lc from the link.
# This causes us to have to jump through some hoops...
#
# To produce libgcc.mk to edit we firstly require libiberty.a,
# so we configure then build it.
# Next we have to configure gcc, create libgcc.mk then edit it...
# So much easier if we just edit the source tree, but hey...
