tools: Support relative directory path for 'O='

Running "make O=foo" (with a relative directory path) fails with:

  scripts/Makefile.include:3: *** O=foo does not exist.  Stop.
  /home/jpoimboe/git/linux/Makefile:1547: recipe for target 'tools/objtool' failed

The tools Makefile gets confused by the relative path and tries to build
objtool in tools/foo.  Convert the output directory to an absolute path
before passing it to the tools Makefile.
