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.

Import the 32-bit version of SoftFloat 2a and separate it and the 64-bit version into different directories. Which version a given port uses is controlled by the SOFTFLOAT_BITS make variable. This is set to 64 (which uses the same code we had before) by default. 32-bit platforms that don't need extended precision support might get better performance by using 32. Set the ARM port to use the 32-bit version of SoftFloat, since this is more than a factor of two faster than the 64-bit version. This should get the floating-point performance back to what it was in 1.5.

Assign quad / softfloat specific ${SRCS} to ${SRCS.quad} / ${SRCS.softfloat} then append them to ${SRCS}. Those will be used to generate quad / softfloat symbol lists.

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.
