| |
This was a long-standing bug, relative pathnames like O=dir did not fully work in the build system:
$ make O=localdir clean
SUBDIR Documentation ../../scripts/Makefile.include:3: *** O=localdir does not exist. Stop. make[1]: *** [clean] Error 2 make: *** [clean] Error 2
Fix this by canonizing the directory before passing it to Makefile.perf.
