perf tools: Allow cross compiling
For embedded platforms, we want to be able to build the perf
tools on a build machine to run on a different arch. This patch
allows $CROSS_COMPILE to set the cross compiler.
Additionally, if NO_LIBPERL is set, then don't use perl include
paths as they will be for the host arch.
