Yann E. MORIN" 1b9a490601 Some people are reposrting that ftp does not work on their network, probably due to proxies, while http does work.
Some (most) of the sites we use toretrieve tarballs have http equivallent for the ftp service. Use http as a failover.
There's no solution for those sites that do not have such an http equivalent.

# 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...
