+Based on gcc-3.4.0/gcc-3.3.3h-ppc-asm-spec.patch
+
+Fixes the following errors when building gcc for ppc7450:

+
+Note that the "-mcpu=7450" option must appear on the "gcc" command line in
+order for "-maltivec" to be passed to the assembler.  Or, "-maltivec" itself
+may be passed to the "gcc" command.
