cross-compile failures

[Neal Becker]

I have been looking into cross-compile failures I have reported.  The
problem is building libiberty.

--------------

The problem is that we are using the target compiler, but not using
the target includes.

We have in /src/m68k/egcs-971201/m68k-unknown-coff/libiberty/Makefile:

errors: dummy.o $(EXTRA_OFILES)
	-($(ERRORS_CC) -o dummy $(CFLAGS) $(LDFLAGS) $(ERRORS_LDFLAGS) dummy.o $(EXTRA_OFILES) $(LOADLIBES)) >errors 2>&1 || true


When executed we get this:
(/src/m68k/egcs-971201/gcc/xgcc -B/src/m68k/egcs-971201/gcc/ -o dummy
-g -O2   dummy.o  ) >errors 2>&1 || true

The problem is, if we are going to use the target compiler we need to
add target includes and libs.  Why isn't this being done?  Even if I
say --with-headers=/usr/local/m68k/m68k-unknown-coff/include I still
get the same failure.
