Retiring __ABICALLS__

[Joerg Sonnenberger <joerg%bec.de@localhost>]

Hello all,
GCC has moved to defining __mips_abicalls when -mabicalls is used a long
time ago for the generic MIPS code. Since we have our own copy of that
code to reduce namespace pollution, we never got that switch. I don't
see a good reason for keeping our macro, so I'd like to just switch the
in-tree GCC and the handful of users in the tree to the new name.

Comments? Objections?

Joerg
