This is OK.

Yes, we can use tools from target/tools/, that's the whole idea of
"tools".
We just must not link to anything there, we can only link to
target/linux-x86. It seems from this snippet
conftest.c:2:1: warning: this is the location of the previous definition
/home/lilypond/gub/target/tools/root/usr/lib/libexpat.so.0: undefined
reference
to `__stack_chk_f...@glibc_2.4'
that something links to tools. You can try running the failed gcc
command, possibly using --verbose or -Wl,--verbose to see how we
pick-up tools.

technically we're not cross compiling, but GUB just pretends that we
are. I don't even think building/using a contained toolchain will
work otherwise.
