mmap test

mmap test

[Andrej Borsenkow]

I noted, that configure for libiberty has a bit better test for mmap() that
also tests for usability of it. Can we simply include it? Do we need to ask
permissions from ehh FSF? RMS?

No, it's probably GPL'd.

We should just use the autoconf AC_FUNC_MMAP test.

It used wrong cache variable.

I also removed CYGWIN cludge from system.h now when test for mmap works.

(Line numbers in configure.in may be a bit off)
