Supporting PIC32 means a few things:

1.  Uglier asm code.
2.  Someone must be willing to maintain PIC32, and furthermore be
willing to add PIC32 to all new assembly functions written.  This is a
lot of work.
3.  Having to deal with all the people who inadvertently enable it, as
it costs 4-5% speed.

It was removed because nobody was willing to do 2), and we were sick
of 1) and 3).  It isn't just a case of "macros"--you need a lot of
special-casing to deal with the fact that PIC requires an extra
register... which as you may know are in rather short supply on
x86_32.
