spar-rtems add leon3 multlib to 4.9

[Joel Sherrill]

I would like to add this patch to the 4.9 branch. It is RTEMS
specific and takes advantage of the leon3 multilib support from
Eric Botcazou. 

OK to commit?

Re: spar-rtems add leon3 multlib to 4.9

Hello,

I would ideally like the mcpu=leon3v7 patch applied first (https://gcc.gnu.org/ml/gcc-patches/2014-08/msg02035.html), so that we can change the multi lib patch to include the leon3v7 target. I believe 
it would be good for the RTEMS LEON3 BSP to include support for all LEON3/4 processors. If switching to mcpu=leon3 in RTEMS BSP, then we no longer support the LEON3 V7 processors.


Best Regards,

Hello Joel,

this is the wrong patch.  We need also the user mode CAS variants for 
hypervisor support, e.g.


https://gcc.gnu.org/ml/gcc-patches/2014-05/msg00057.html

We should also wait for Daniel's latest stuff.
