There is however no harm from having it.

Ths situation is similar also with DJGPP port of GCC - cross-compiler
SRPM have all patches including those used for native compiler only.
Side product of building cross-compiler RPMs is also GCC source
archive for DJGPP (which I move to Windows for building native compiler)
