2.6.33-stable review patch. If anyone has any objections, please let us know.

------------------

From: John Kacur <jkacur(a)redhat.com>

commit 7ae5f21361fea11f58c398701da635f778635d13 upstream.

Without this change, the install path is relative to
prefix/DESTDIR where prefix is automatically set to $HOME.

This can produce unexpected results. For example:

make -C tools/perf DESTDIR=/home/jkacur/tmp install-man

creates the directory: /home/jkacur/home/jkacur/tmp/share/...
instead of the expected: /home/jkacur/tmp/share/...
