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.
