[OpenRISC] GCC multilib for multicore?

[Stefan Wallentowitz]

Hi all,

I am nearly done with newlib now and work on the reentrancy stuff. I
found it may make sense to have two different libraries when using
multicore. In the moment I have a gcc option multicore
(https://github.com/wallento/or1k-gcc/blob/multicore/gcc/config/or1k/or1k.opt#L98)
and built two versions of libgloss' libor1k and crt0
(https://github.com/wallento/or1k-src/blob/multicore/libgloss/or1k/Makefile.in#L90).
GCC then collects the correct one depending on the presence of the
multicore flag
(https://github.com/wallento/or1k-gcc/blob/multicore/gcc/config/or1k/or1k.h#L61).
Although the whole rest of newlib does not need to compiled twice, I am
not sure if multilib is the proper way to do this. Any opinions?

Thanks,
Stefan
