Revert handling of divide and remainder assembler pseudo-ops (with
...
test for divide-by-zero, unlike machine insn) from the binutils-2.9.1
sequence to the older binutils-2.8.1 sequence.
gas 2.8.1 emits a div as (in pseudocode)
divu $zer0o, a0, v0; bnez $v0, 1f; nop; break0x7; 1: mflo a0;
gas 2.9.1 emits the shorter sequence
bnez <divisor>, 1f; divu <args>; break0x7; 1:
bnez $v0, 1f; divu $zer0o, a0, v0; /break0x7; 1: mflo a0;
but that on a decstation 5000/150 with a rev 3.0 r4000, for kernel
code, later references to $a0 seem to get a corrupted value. not
reproduced yet on an r4400.
Could be an r4000-specific bug with the interlock on mulhi and mullo?

Make it a tad bit easier to bootstrap an a.out system to ELF. Introduce
...
a BOOTSTRAP_ELF Makefile variable that, when set (e.g. in the environment),
builds a targeted-to-ELF toolchain without requiring OBJECT_FMT to be set
to "ELF" (which affects how e.g. libraries are built).
This basically means you don't need fake crtbegin.o and crtend.o files to
be present in /usr/lib while bootstrapping the toolchain.
