tools build: Fix Makefile(s) to properly invoke tools build
Several fixes were needed to allow following builds:
$ make tools/tmon
$ make -C <kernelsrc> tools/perf
$ make -C <kernelsrc>/tools perf
- some of the tools (perf) use same make variables as in
kernel build, unsetting srctree and objtree
- using original $(O) for O variable
- perf build does not follow the descend function setup
invoking it via it's own make rule
I tried the rest of the tools/Makefile targets and they
seem to work now.
