Clean up architecture handling in configure.ac

Browse Source 
Remove the need for two variables for the architecture-specific switches
(things like "-march=i686") by combining it into one variable. Also allow
configure to proceed with only a warning if we don't have presets for the
detected architecture- it is kind of stupid to restrict ourselves like we
had been.
