[PATCH] support CROSS_COMPILE environment variable

[Tim Bird]

Thanks for the great utility!

I'm using powertop on a non-Intel target platform, and needed
to cross-compile for my board.  I found instructions for this
by Googling (this list), but I thought it might be handy
to document this and also support the use of the CROSS_COMPILE
environment variable (which is the same as what the kernel uses
for this).

Here's a patch.  Use, or not, at your discretion.
