[PATCH/TopLevel] Fix compiling libgo with a combined sources

[Andrew Pinski <pinskia at gmail dot com>]

Hi,
  The problem here is here is that OBJCOPY is not being set to the
newly built objcopy when compiling libgo.  This patch adds
OBJCOPY_FOR_TARGET to the toplevel configure/Makefile so that when
libgo is compiled OBJCOPY is set to OBJCOPY_FOR_TARGET.

I noticed this issue when building an aarch64 cross compile on an
older system where objcopy did not understand aarch64.

OK?  Bootstrapped and tested on x86_64 with no regressions.  Also
tested with a combined build for a cross compiler to
aarch64-linux-gnu.

Thanks,
Andrew Pinski


        * Makefile.def (flags_to_pass): Pass OBJCOPY_FOR_TARGET also.
        * Makefile.tpl (HOST_EXPORTS): Add OBJCOPY_FOR_TARGET.
        (BASE_TARGET_EXPORTS): Add OBJCOPY.
        (OBJCOPY_FOR_TARGET): New variable.
        (EXTRA_TARGET_FLAGS): Add OBJCOPY.
        * Makefile.in: Regenerate.
        * configure.ac: Check for already installed target objcopy.
        Also GCC_TARGET_TOOL on objcopy.
        * configure: Regenerate.
