Subject: [PATCH 3/3] kbuild, bloat-o-meter: fix static detection

From: Andi Kleen <ak@...ux.intel.com>

Disable static detection: the static currently drops a lot of useful information
including clones generated by gcc. Drop this. The statics will appear now
without static. prefix.

But remove the LTO .NUMBER postfixes that look ugly
