First target in Makefile is `install'.
With this, simple `make' call from .spec will build and install
things at /sbin/bdflush.

Can anybody audit all packages to be buildable as non-root and
thus preventing that ugly bug(s)?!
I already posted tons of bugreports about similar problems
(missing `%defattr(-,root,root)', stupid `install -u0 -g0',
modification of system files when building etc etc...)
