From: Joel Sherrill <j...@rtems.org> * 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.
