2d8577fb83 Clean up some rampant code duplication wrt ieee number handling: 
- Add alignment-safe double and float unions.
 - Use the above for the __infinity and __nan constants on all
   architectures that use the standard ieee754 representation of
   those constants.
 - Add a single copy of various ieee754 math functions (frexp, isinf,
   isnan, ldexp and modf) that had numerous duplicates among the
   arch-specific directories.
 - Use the above functions on all architectures where the generic C
   versions where used.  Architectures that had local assembly
   routines are untouched (for those functions only).

6d536163de Change defaults for kernel compiles. Default all to USETOOLS?=no and have 
the etc Makefile override that by putting USETOOLS into $.MAKEOVERRIDES
This way the default for kernel compiles is still to use the installed
toolchain instead of depending on $TOOLDIR. $TOOLDIR can be used by
simply adding USETOOLS=yes to the command line as usual.

Adjust each ports template to set the default no setting and also pull in
bsd.own.mk if they weren't already to ensure they'll build correctly
with the new toolchain setup.

0e7661f023 Update pmap_update to now take the updated pmap as an argument. 
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.

59abdecf4b Add a linux specific trapsignal() function. This is just a passthrough 
on all platforms but the i386. On the i386 we look at T_PROTFLT and send
a SIGSEGV instead of SIGBUS. This makes allegro lisp 5.0 and pvs (a proof
verification system) to work.

XXX[1]: We need to go through each architecture and verify that we send
        the correct signal on each trap type.
XXX[2]: trap.c on all other architectures but i386 needs to be modified
        to s/trapsignal/(*p->p_emul->e_trapsignal)/g
