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.
