Add TFLAGS to gcc's GCC_FOR_TARGET
When the GCC build runs GCC_FOR_TARGET, e.g. for selftests or for
dumping specs, it doesn't use TFLAGS in non-bootstrap scenarios. This
patch arranges for TFLAGS to be passed from the top level down to gcc
in GCC_FOR_TARGET in this case.
Another issue related with TFLAGS fixed herein is that there's no easy
way to add a TFLAGS to GCC_FOR_TARGET when running "make gnatlib"
within the gcc directory. Overriding all of GCC_FOR_TARGET is
somewhat cumbersome, so I'm adding TFLAGS support to gcc/Makefile.in,
getting it added to GCC_FOR_TARGET, as it would when passed down from
the top level.
for ChangeLog
* Makefile.tpl (HOST_EXPORTS): Add TFLAGS to GCC_FOR_TARGET.
(EXTRA_GCC_FLAGS): Likewise.
* Makefile.in: Rebuilt.
for gcc/ChangeLog
* Makefile.in (TFLAGS): New.
(GCC_FOR_TARGET): Add TFLAGS.
(FLAGS_TO_PASS): Pass TFLAGS down.
