  Modified:    etc       make.conf

  Added:       lib/msun/src  get_hw_float.c
  Log:
  Select between the generic math functions and the i387-specific ones
  at runtime.
  
  etc/make.conf:
  Nuked HAVE_FPU option.
  
  lib/msun/Makefile:
  Always build the i387 objects.  Copy the i387 source files at build
  time so that the i387 objects have different names.  This is simpler
  than renaming the files in the cvs repository or repeating half of
  bsd.lib.mk to add explicit rules.
  
  lib/msun/src/*.c:
  Renamed all functions that have an i387-specific version by adding
  `__generic_' to their names.
  
  lib/msun/src/get_hw_float.c:
  New file for getting machdep.hw_float from the kernel.
  
  sys/i386/include/asmacros.h:
  Abuse the ENTRY() macro to generate jump vectors and associated code.
  This works much like PIC PLT dynamic initialization.  The PIC case is
  messy.  The old i387 entry points are renamed.  Renaming is easier
  here because the names are given by macro expansions.
