gcc/build-make wrongly disables fixinc

the fragment gcc/build-make is included when build!=host .
it disables fixinc by including the lines:
# To build the native compiler with the cross compiler, the headers
# for the target are already fixed. And /usr/include is for host, not
# target.
STMP_FIXINC =
STMP_FIXPROTO =
however, if you're building a canadian cross (such as
hpux-x-cygwin-x-aix), then you do need to apply fixinc to
the target headers in $(tooldir)/sys-include .
another symptom is: since sys-include/limits.h exists, gcc
will create a limits.h that wants "syslimits.h", but
syslimits.h won't exist since it's only created by the
stmp-fixinc target.
this patch is based on the theory that it's harmless to run
stmp-fixinc when sys-include is nonexistent or empty.
if this patch is correct, then I don't see a reason for
STMP_FIXINC any more, and it can probably be deleted.
STMP_FIXPROTO still looks necessary though.

* build-make: sometimes we do need to run fixinc.
