[PATCH] D14292: [libcxx] Make it possible to build a no-exceptions variant of libcxx.

[Asiri Rathnayake via cfe-commits]

rmaprath created this revision.
rmaprath added reviewers: rengolin, mclow.lists.
rmaprath added a subscriber: cfe-commits.

Fixes a small omission in libcxx that prevents libcxx being built when 
-DLIBCXX_ENABLE_EXCEPTIONS=0 is used.

I will do a follow-up patch to introduce the new libc++ build to the buildbot.
