Subject: Fix build on FreeBSD
X-Git-Tag: 0.10.0-0maemo1~1021
X-Git-Url: http://git.maemo.org/git/?a=commitdiff_plain;h=997306fc2246048b9a4e8df4b4bb96eab6c65a82;p=qemu

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.
