[google gcc-4_8] Force cmd-line match for option -ansi in LIPO use

[Rong Xu]

The following patch forces the command line match for -ansi option
in LIPO use build. Otherwise, it gets various undefined symbol errors.
This is exposed in LIPO random grouping test.

Tested with google internal benchmarks and gcc regression test.
