[PATCH] Propagate -ffile-prefix-map from CFLAGS to ASFLAGS.

[Khem Raj]

-ffile-prefix-map could be used as superset to imply -fdebug-prefix-map
as well, therefore it should be propagated too, so cases when
-ffile-prefix-map is used but -fdebug-prefix-map is not, then it should
still rewire the paths in debug info
