[Qemu-trivial] [PATCH 1/2] [RESENT-INLINE] Use libtool instead of ar to

From: Christopher Friedt
Subject: [Qemu-trivial] [PATCH 1/2] [RESENT-INLINE] Use libtool instead of ar to create static libraries on Darwin.
Date: Mon, 2 May 2016 21:01:04 -0400

Currently, at least on Mac OS X 10.11.4 (El Capitan), Qemu fails to build for a 
few reasons.

One of those reasons is that Apple's ld (at least ld64) does not properly 
process archive files created with ar (even Apple's ar).

After some RTFM'ing, I came upon this tidbit, which is unfortunate. Luckily, 
autotools packages are not broken.

"Libtool with -static is intended to replace ar(5) and ranlib."

In any case, this change takes Apple's recommendations into account and allows 
Qemu to build on Mac OS X El Capitan.
