add56503a4
This is the compantion patch to https://reviews.llvm.org/D64482, needed to ensure that builds with host compilers that don't yet predefine _FILE_OFFSET_BITS=64 on Solaris succeed by always making the host and freshly built clang consistent. Tested on x86_64-pc-solaris2.11. Differential Revision: https://reviews.llvm.org/D64483 llvm-svn: 367304
