Subject: Do not try to descend into optional build directories if they do not
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=c156632c62214c7d611f187e148c51e8ed4060d5;p=oota-llvm.git

Do not try to descend into optional build directories if they do not
exist.  This makes the build logic symmetric for both the in tree and
out of tree cases.
