Was it ever supposed to work?  As far as I can see in Makefile.inc1, it
is only supposed to build binutils and gcc, but nothing clang-related.

In any case, to build clang, you also need to build tblgen and
clang-tblgen as bootstrap tools, otherwise you might end up with
incorrectly generated .inc files.  This is most likely the cause of the
errors you list above.

If the only purpose of xdev is to build binutils and gcc, the easiest
solution is probably to exclude the clang libraries from the
_xi-libraries target, for example by setting WITHOUT_CLANG to a
non-empty value.
