xserver-xorg: Fix build for mips64

mips64 N64 ABI has different size for int and pointer
which means the compiler will complain about conversions
which works fine for 32 bit since sizes are same.

amd64 is taken care of already so we take care of mips64
with this patch by understanding the difference in sizes
in compiler.h

+on mips64/n64 pointers are 64bit therefore the pointer conversions to int dont work well
+so we end up with incompatible conversion errors
+
+This patch choses the right values for mips64
