swscale: try to use mmap only if available
Some systems, e.g. Minix, have sys/mman.h defining MAP_ANONYMOUS without providing (working) mmap and friends. The mmx filter generation code checks only for MAP_ANONYMOUS, not for availability of mmap itself which leads to build errors on aforementioned systems. This changes the conditional compilation to use mmap only if all the required functions are available. Signed-off-by: Mans Rullgard <mans@mansr.com>
