tools/power: turbostat: make Makefile a bit more capable
The turbostat Makefile is pretty simple, its output is placed in the
same directory as the source, the install rule has no concept of a
prefix or sysroot, and you can set CC to use a specific compiler but
not use the more familiar CROSS_COMPILE. By making a few minor changes
these limitations are removed while leaving the default behavior
matching what it used to be.
Example build with these changes:
make CROSS_COMPILE=i686-wrs-linux-gnu- DESTDIR=/tmp install
or from the tools directory
make CROSS_COMPILE=i686-wrs-linux-gnu- DESTDIR=/tmp turbostat_install
