config/i386/t-rtems: Change from mtune to march for multilibs
* config/i386/t-rtems: Change from mtune to march when building
multilibs. The mtune argument tunes or optimizes for a specific
CPU model but does not ensure the generated code is appropriate
for the CPU model. Prior to this patch, i386 compatible code
was always generated but tuned for later models.
