Hey!
It seems like the RSB patch for crt[i/n] was mistakenly taken out
along with other stuff:
https://git.rtems.org/rtems-source-builder/commit/?id=258129e140a2f0c7f579492bda2a86c6c1b93080
I'm on a new computer where I'll have to compile git from source to
use `send-email` to send the patch, so I've just attached it here -
hope that's okay! (I can send it properly tomorrow if we want the
community to review it.)
I've tested that with this patch, the RTEMS kernel does successfully build.

Subject: [PATCH] 5: Fix x86_64 GCC build to include crt[in].o
This was mistakenly removed in commit 258129e, but is still required.
