           Summary: clang: tests unable to find hmaptool in stand-alone
                    builds

           Version: 7.0
          Hardware: PC
                OS: Linux

The following clang tests fail in stand-alone builds:

********************
Failing Tests (5):
    Clang :: Modules/double-quotes.m
    Clang :: Modules/framework-public-includes-private.m
    Clang :: Preprocessor/headermap-rel.c
    Clang :: Preprocessor/headermap-rel2.c
    Clang :: Preprocessor/nonportable-include-with-hmap.c


The issue is wrong path to hmaptool:

I've submitted a potential fix as https://reviews.llvm.org/D50156.  Once it's
committed to trunk, please backport to release_70.
