Hi Sebastian:
LGTM, I've test riscv32-rtems-gcc is buildable.
Thanks for you patch :)
Hi Palmer:
Could you help to commit this patch ?
Thanks.

It appears to work for me: I can generate a simple no-op executable and link it
with multilib. I don't know anything about RTEMS, so I'm just going to trust
it'll actually work :). We're not going to have bandwidth to test this, but if
you're interested there's some support for running the GCC test suite in our
super-repo
https://github.com/riscv/riscv-gnu-toolchain
I committed the patch as
https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=250632
Thanks a bunch!
