[PATCH 1/3] xfsprogs: misc uClibc patches: remove aio.h check from configure

[Joshua Kinard]

From: Joshua Kinard <kumba at gentoo.org>

Remove the configure check for aio.h, which is not provided by uClibc, and
which does not appear to be used by xfsprogs.

Refer to Gentoo Bug #477758:
https://bugs.gentoo.org/show_bug.cgi?id=477758
