Jordan K. Hubbard 1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

* $FreeBSD$

* Simple SPARC relocations for the benefit of self-relocation of ld.so
* avoiding the use of global variables (ie. reloc_bitshift[] et. al.).
* Only types supported are RELOC_32 and RELOC_RELATIVE.
*
* This *must* be a static function, so it is not called through a jmpslot.
