posix_fallocate is not detected by configure

[anonymous]

when I specify these options "--with-fallocate --with-posix-fallocate" (don't which one is the good option) on the configure command line, posix_fallocate is never detected. Also when no option is specify. I"ve made the test using a debian sarge on x86-64 and glibc-2.3.2.ds1-22.

... checking for epoll support... yes checking for pkg-config... /usr/bin/pkg-config checking for openssl... yes ...

A quick dirty patch, is too change the file scripts/checks.m4

I think the test is bogus, and need to be remove.

It's wrong and never used, but not bogus. The intent is to allow posix_fallocate to be used on newly created files, but no OS i know of has a good implementation of it yet. So it is by default turned off. I'll fix the test to work properly.
