Add support to build the mac68k port with soft-float enabled (i.e., setting MKSOFTFLOAT=yes). The main purpose of this feature is to let NetBSD work in machines with the 68040LC chip (those that have the FPU bug). All the work has been done by Bruce O'Neel <edoneel AT sdf.lonestar.org>, with some very minor changes by me; the patches were being posted to the port-mac68k mailing list. It has been tested for a long time by several users, including me. I have just verified that regular releases, as well as soft-float ones, continue to build. There have been no objections to this patch since I asked for them in July in the port-mac68k list.

/* $NetBSD: softfloat-for-gcc.h,v 1.7 2004/09/26 21:13:27 jmmv Exp $ */
Initial commit of SoftFloat 2a import. This should provide a sensible mostly-MI floating-point implementation for use by gcc -msoft-float. It's currently only used by arm26, but should be usable by other ports without too much hacking, assuming doubles and u_int64_ts are passed and returned the same way, and FP formats are IEEEish.

#define float_exception_flags _softfloat_float_exception_flags
Add SIGFPE support to SoftFloat, so fpsetmask/fpgetmask now work. A new variable, float_exception_mask (#defined to _softfloat_float_exception_mask) contains the current exception mask. Also make the argument to float_raise into an fp_except. Also synchronise file header comments between files.
