Regarding --with-sysroot, should that be run only with binutils configure and the final gcc configure? It seems that using this configure flag with the bootstrap configure doesn't make any sense...probably not with the kernel headers either...but what about glibc? For my next experiment, I'll try just with binutils and the final gcc compile to see if that works...
Correct. Also, if you're building gdb, that needs it, too, I hear.
Does the path pointed to by --with-sysroot have to pre-exist?
Yes, according to http://www.redhat.com/docs/manuals/gnupro/GNUPro-Toolkit-03r1/gnupro_9.html
(See also http://gcc.gnu.org/install/configure.html, which says if you use --with-sysroot, you shouldn't use --with-headers or --with-libs.)
See also http://linuxfromscratch.org/~tchiwam/XCompilerLinuxGlibc (Seems he used --with-sysroot when building the bootstrap compiler - hmm, didn't think that'd be needed, but it makes sense. He didn't with binutils; I bet he hasn't tried moving the resulting binaries to a different location yet.)
A couple other examples: http://www.myownlittleworld.com/computers/solaris-cross.html http://www.linux-france.org/~dmentre/doc/en/ixp2400-linux-toolchain-howto.txt
BTW, I noticed there's a bug filed against sys-root; not sure if it affects us: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=12561
