+[PATCH] sparc32: Add -Av8 to assembler command line.
+
+Newer version of binutils are more strict about specifying the
+correct options to enable certain classes of instructions.
+
+The sparc32 build is done for v7 in order to support sun4c systems
+which lack hardware integer multiply and divide instructions.
+
+So we have to pass -Av8 when building the assembler routines that
+use these instructions and get patched into the kernel when we find
+out that we have a v8 capable cpu.
