rS366636: Enable SUBDIR_PARELLEL in lib/libclang_rt

Summary

I noticed that this part of the build was taking much longer than
expected. Turns out it's due to not running the subdirs in parallel.
Reduces make all inside lib/libclang_rt time from 63s to 20s with -j32.

ping?

Ah yes, this is OK. There's probably some more optimization possible, since these libraries build lots of duplicated object files, but I haven't had the time to look at that yet.
