build: overhaul build system auto detect stuff using a configure script

The new build instructions are:

 $ ./configure && make && sudo make install

The configure script tries to auto detect support for various libraries
and compiler options. These choices can be overwritten by explicitly
specifing --{en,dis}able-{lua,selinux,acl}. See ./configure --help for
all supported options.

The configure script generates config.mk which should allow portable
(among GNU and BSD make) Makefiles. Manually editing config.mk is
still supported.
