# @LOCALMOD-START The PNaCl driver automatically adds dependencies to
#                 libc++ which hasn't been built yet. The tests for
#                 flags therefore fail because the library can't be
#                 found. We should fix this in a different CL, and add
#                 proper detection for newlib's lack of locale_t
#                 support. See:
#                  https://code.google.com/p/nativeclient/issues/detail?id=3661
