Peter Zijlstra 99d0021569 objtool: Add a pass for generating __mcount_loc
Add the --mcount option for generating __mcount_loc sections
needed for dynamic ftrace. Using this pass requires the kernel to
be compiled with -mfentry and CC_USING_NOP_MCOUNT to be defined
in Makefile.

[Sami: rebased, dropped config changes, fixed to actually use --mcount,
       and wrote a commit message.]
