while reusing PGO data is fine, i don't really see the point of changing DISTFILES.profdata (and having to make it ?= in moz.port.mk), setting FFDIST & FFVERSION since in all cases it wont share it with firefox as DIST_SUBDIR is set to something different, and it'll get fetched a second time with the same name but in that distinct DIST_SUBDIR. at that point.. oh well. i don't really care either way :)
