This fix causes the below error in linux-next:

install: cannot create regular file '/usr/lib64/pkgconfig/libperf.pc': Permission denied
make: *** [Makefile:210: install_pkgconfig] Error 1                             

I am posting a follow-up fix. To me the end result does not look
nice, as do_install and do_install_mkdir are inconsistent, but
the above error goes away.

Thanks!
