The bootstrap breaks in stage1 when trying to build libgcc for
multilib (this is sparc-unknown-linux with "--enable-targets=all"):
make[3]: Leaving directory `/home/davem/src/GIT/GCC/build-sparc-linux/gcc'

It's using "linux.h" instead of "linux-unwind.h" for whatever reason.
So we need something like this?

just another typo, and installed the following as obvious.
Sorry for the mess.
