gcc-5.3/gcc-4.9:replace build path with target path in __FILE__
Similar -fdebug-prefix-map, add option -ffile-prefix-map to map one
directory name (old) to another (new) in __FILE__, __BASE_FILE__and
__builtin_FILE ().
With this patch, it fixes build path issue which caused by __FILE__.
We do not need to use relative path to compile any more.
