[PATCH] Small fix for x86_64 testsuite bug

- Subject: [PATCH] Small fix for x86_64 testsuite bug
This patch fixes a testsuite test failure on x86_64 linux targets where the
built gcc is 64-bit and the native C compiler is, for whatever reason, 32-bit
by default.
The test links an object file from the built gcc with an object file from the
native C compiler, and so invokes the native C compiler. The architecture
of the object file built by the native C compiler must match that of the
object file from the built gcc; if not, the link and the test fail.
The patch adds -m64 to the native C compilation if the file being linked to
from the built gcc is a 64-bit object.
Tested and confirmed with gcc testsuite. Okay for mainline?

* gcc.misc-tests/linkage.exp: Added -m64 to x86_64 linux target
native C compilation where required.
