Note that there's also a few other problems needing to be patched, at
least on Ubuntu 8.10, to start with, needing
https://dev.openwrt.org/browser/trunk/toolchain/gcc/patches/3.4.6/820-i386_inhibit_libc.patch?rev=14370
and I'm trying to nail down a glibc that builds with all of this as
well (2.2.5 had some problem for DISTRO=angstrom-2008.1 MACHINE=epia).
All in all, I'm about to give up on 3.* (I was building for some SDK
patches I'm going to post shortly, need to get back to testing that
stuff..)
