[PATCH 1/3] RTEMS: Use MULTILIB_REQUIRED for PowerPC

2014-12-15 Thread Sebastian Huber 
This patch should be applied to GCC 4.9 and mainline.  I do not have
write access, so in case this gets approved, please commit it for me.

gcc/ChangeLog
2014-12-15  Sebastian Huber  sebastian.hu...@embedded-brains.de

* config/rs6000/t-rtems: Use MULTILIB_REQUIRED instead of
MULTILIB_EXCEPTIONS.
