tools: Let O= makes handle a relative path with -C option
When I tried to compile tools/perf from the top directory with the -C
option, the O= option didn't work correctly if I passed a relative path:
$ make O=BUILD -C tools/perf/
make: Entering directory '/home/mhiramat/ksrc/linux/tools/perf'
BUILD: Doing 'make -j8' parallel build
../scripts/Makefile.include:4: *** O=/home/mhiramat/ksrc/linux/tools/perf/BUILD does not exist. Stop.
make: *** [Makefile:70: all] Error 2
make: Leaving directory '/home/mhiramat/ksrc/linux/tools/perf'
The O= directory existence check failed because the check script ran in
the build target directory instead of the directory where I ran the make
command.
To fix that, once change directory to $(PWD) and check O= directory,
since the PWD is set to where the make command runs.
Fixes: c883122acc0d ("perf tools: Let O= makes handle relative paths")
