SBCL 1.0.46

Allow SBCL to be built with or without support for native OS
threads. The default is to build with threads included. The command
line option --without-threads disables them.

Also, add two other options for useful things that can be included in
the build:

 * --with-ldb builds with the low-level debugger (invoked when SBCL
   crashes hard)

 * --with-internals-xref includes XREF information for internal
   functions. This increases the size of the core file by 5-6 MB, but
   is useful if you want to figure out how SBCL works.
