Mac OS X Support : General PowerPC fix for gcc in interlocked.c

["Pierre d'Herbemont" <stegefin@free.fr>]

Hi,

Here is an other fix for the powerpc interlocked functions.

Thanks,

Pierre

Modified files:
libs/port/interlocked.c

ChangeLog:
Add register preservation when using lawrx instruction . Also fix ';' 
ending to '\n' ending for a better compatibility with darwin's ld.
