From 513cdb44a6bf866a893275538a19bfee8c7f465d Mon Sep 17 00:00:00 2001

Subject: [PATCH] BUILD: Introduced new env var 'LD' analog to CXX (and
 defaulting to CXX), currently only used for PS2; modified cross compiler
 testing code to only compile but not link the test C++ file (working around
 another PS2 issue); some tweaks to the PS2 related build code
