audio/pulseaudio OS X configure patch

[Mansour Moufid <mansourmoufid%gmail.com@localhost>]

Hello,

If you build PulseAudio on OS X, you need to set the configure options
--with-mac-version-min and --with-mac-sysroot.  This is already done
for OS X 10.6 in the Makefile.

The following patch sets these options for OS X 10.8, 10.9 and 10.10,
according to the output of the xcrun command which uses the SDKROOT
environment variable.  Set SDKROOT in your etc/mk.conf file, to the
full path of the first SDK printed by:

    xcodebuild -sdk -version

Yours,
Mansour
