I can. I would rather not, because when you don't have prefix set to
/usr you get a different glibc build. For example, on aarch64 building
with --prefix=/usr means that libraries are put in lib64 (or libilp32)
instead of just lib. The glibc folks are always preaching against
building with a prefix of anything other than /usr.

Ah, I see. I was hoping that using --with-advance-toolchain would give
me a way to build a toolchain without needing any local/non-standard
patches.
