[PATCH] tools: Allow tools to be installed in a user specifiedlocation

[Josh Boyer]

When building x86_energy_perf_policy or turbostat within the confines of
a packaging system such as RPM, we need to be able to have it install to
the buildroot and not the root filesystem of the build machine.  This
adds a DESTDIR variable that when set will act as a prefix for the
install location of these tools.
