CROSS_COMPILE is defined. I tracked the problem down now,
egcs-971201/configure.in and egcs-971201/gcc/Makefile.in don't agree on
the location for the cross headers:

configure (see egcs-971201/configure.in) copies the headers to

    ${prefix}/${target_alias}/sys-include

while egcs-971201/gcc/Makefile.in defines CROSS_INCLUDE_DIR to be

    $(libsubdir)/sys-include

with libsubdir = $(libdir)/gcc-lib/$(target_alias)/$(version)

So these two directories are clearly different, but which one is the
right one?
