[Lldb-commits] [PATCH] D22233: Apply local patches when building llvm on Mac.

[Stephane Sezer via lldb-commits]

sas created this revision.
sas added reviewers: tfiala, clayborg.
sas added a subscriber: lldb-commits.

This is already done when building for linux with the CMake build
system. This functionality disappeared recently when some of the build
scripts used by the xcode build system changed.
