"[MIPS] Change libgcc-style functions from lib-y to obj-y"
(sha1: f7c27781),
switch the goal definition for kbuild to obj-y to ensure
object files linked in vmlinux if only modules were users
of these functions.

- Do not trace idle loop which takes a lot time
- Fix cache handling in generic ftrace code
- Do not trace lib functions ashldi3, ashrdi3, lshrdi3
  Functions are called from generic ftrace code which
  can't be traced

The microblaze checksum code is mostly identical to
the asm-generic+lib version, so use that instead.
