Notably, the current compat_options only makes sense for native and
freebsd32 ABIs. For the others, it just adds cruft. Switch to having
sets of compat options, and default to the native set. Setup the other
ABIs where it doesn't make sense to opt-out of the native set.
This removes some redundant COMPAT_FREEBSD* stuff from Linuxolator bits.
line_expr in makesyscalls.lua is fixed to allow empty strings to be
specified, since they're harmless.

- Send the systrace_args files for all the compat ABIs to /dev/null for
now. Right now makesyscalls.sh generates a file with a hardcoded
function name, so it wouldn't work for any of the ABIs anyway. Probably
the function name should be configurable via a 'systracename' variable
and the functions should be stored in a function pointer in the sysvec
structure.
Gee, I wish there was a better way to run makesyscalls.sh so that
a make world finds missing things like this. Running it manually
sucks.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
