[libc-commits] [libc] [libc] Disabled mpfr tests in full build mode, even if we set the mpfr path (PR #149655)

[Mikhail R. Gadelha via libc-commits]

https://github.com/mikhailramalho created https://github.com/llvm/llvm-project/pull/149655

If we are doing a full libc build, mpfr tests should be disabled even if we set the mpfr path. This patch simply swaps the check order.

This should fix the rv32 buildbot.
