gcc-patch: Add patch for 4.4.5 to support Sparc-leon processors
Gcc patch that adds hfleon (fpu,v7), hfleonv8 (fpu, v8), sfleon (softfpu,v7), sfleonv8 (softfpu,v8) SPARC variants. Default cpu is selected with --with-cpu. Adds leon pipeline descrption to gcc. Signed-off-by: Konrad Eisele <konrad@gaisler.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
