Fix build on FreeBSD
__GLIBC_PREREQ is defined in such a way that the ! cannot be used in front of it on FreeBSD. Also, -lpthread is not implied by the build and we definitely use it for compatfd support. While at it, I added a default initialization for posix-aio that seems to perform well in our testing.
