completely override the defaults (including disabling DMA) in the
kernel config file.

96acdadef7 First step inn removing config_scan() and the hacks that gave devices 
on indirect-config busses a (permanent) softc that they could share
between 'match' and 'attach' routines:

Define __BROKEN_INDIRECT_CONFIG so that old autoconfiguration
interfaces are used, until drivers are converted to use the new
interfaces (actually, converted back to use the _older_ interfaces)
which prohibit indirect configuration devices from receiving a softc
in their match routine that they can share with their attach routine.

4c1d96de78 * Replace explicit -O2 in CFLAGS with COPTS macro. Default COPTS?= -O2. 
Lets users over-ride with makeoptions COPTS="..." in kernel config files.

  Leave `mandatory' flags (like  -msoft-float which  on m68k enforces no
  FP in kernel) in CFLAGS.

af0ec0d1d4 installboot(8) now handles required a.out header munging. 
Also, the munging is extended by inserting an instruction that branches
past the header, so the same boot image can be used on all supported
sun platforms.
