There's a long-standing PR that mips-tfile and mips-tdump fail to
compile in a cross. This happens because both refer to non-existant
mips/a.out.h files in the cross-compilation case. Since the tools are
now only used on Tru64 UNIX and gas/gld don't work for that target,
there's no point in trying to build them. Besides, if gas worked,
mips-tfile wouldn't be needed at all.
The following patch only enables them native, and removes cross support
from mips-tfile.c/mips-tdump.c.
Bootstrapped without regressions on alpha-dec-osf5.1b and verified that
a i386-pc-solaris2.10 x alpha-dec-osf5.1b only dies when trying to build
libgcc due to lack of assembler and target headers.
Installed on mainline.

* config.gcc (alpha*-dec-osf5.1*): Only build mips-tfile,
mips-tdump native.
* mips-tfile.c: Remove CROSS_DIRECTORY_STRUCTURE handling.
