Hi Eric.

Took a look at this now and fixed it like this.
Let me know if you see other issues.

[I know this is more than 6 months ago you reported it - sorry]

Subject: [PATCH] kbuild: fix installing external modules

Eric Sandeen <sandeen@...hat.com> reported:
  Installing external modules is supposed to put them in some path
  under /lib/modules/<version>/extra/subdir/, but this change:
  http://linux.bkbits.net:8080/linux-2.6/?PAGE=cset&REV=1.1982.9.23
  makes them go under /lib/modules/<version>/extrasubdir

 (for example, make M=fs/ext3 modules_install puts ext3.ko in
 /lib/modules/<version>/extrafs/ext3.ko)

This was the case only when specifying a trailing slash to M=..

Fixed by removing trailing slash if present so
we correctly match dir part of target.
