From 9b6bbc3d96729c18eef9a3c39021967220bcc5e4 Mon Sep 17 00:00:00 2001 From: Josh Poimboeuf Date: Thu, 3 Mar 2016 08:53:43 -0600 Subject: tools: Support relative directory path for 'O=' commit e17cf3a80d4ba0c4e40bf1a89deb1354c2e10e14 upstream. 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.
