Hello,

The "config" files bits for the x86 families of targets
for which VxWorks 7 support is being introduced.

Just accept the triplets on the libgcc end and handle the
common need of x86-64.h for x86_64 on the gcc front.

Tested together with the previous patches of the vxworks7
series. Committing to mainline.

With Kind Regards,

Olivier

        gcc/
        * config.gcc: Handle i*86-vxworks7 and x86_64-vxworks7.

        libgcc/
        * config.host: Likewise.
