When I compiled tools/bootconfig from top directory with
-C option, the O= option didn't work correctly if I passed
a relative path.

  $ make O=./builddir/ -C tools/bootconfig/
  make: Entering directory '/home/mhiramat/ksrc/linux/tools/bootconfig'
  ../scripts/Makefile.include:4: *** O=./builddir/ does not exist.  Stop.
  make: Leaving directory '/home/mhiramat/ksrc/linux/tools/bootconfig'

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")

<formletter>

This is not the correct way to submit patches for inclusion in the
stable kernel tree.  Please read:
    https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html
for how to do this properly.

Hi Masami,

This patch doesn't fix anything AFAICT.
Didn't help in my testing.

Thanks.

Hmm, what happens on your case? Maybe PWD is not set?

Thank you,

The binary is still built in $srctree/tools/bootconfig/.

If I 'echo $PWD' at a prompt, I get the correct pwd.
