buildbot failure in LLVM on llvm-clang-lld-x86_64-scei-ps4-ubuntu-fast

[Rafael Avila de Espindola via llvm-commits]

"Resource temporarily unavailable" on a clone. I guess too many threads
at once.

Given that std::thread constructor can call abort, I don't think there
is any way for us to handle that gracefully.

We probably need to increase the thread limit on the bot or pin the
tests to a subset of the cpus (which should limit the number of
threads).

Cheers,
Rafael
