TPF stands for "trap false", and is a long-form nop for ColdFire.
Re-use the immediate consumption code from trapcc; the insn will
already expand to a nop because of the TCG_COND_NEVER test
within do_trapcc.

According to the M68040 Users Manual, section 8.4.3, Four word
stack frame (format 0), includes Illegal Instruction. Use the
correct frame format, which does not use the ADDR argument.

Firmware builds require paths to all the binutils; it is not enough to
use only cc, or even as/ld as in the case of tests/tcg/tricore.
Adjust the cross-compiler configurator to detect also ar, nm, objcopy,
ranlib and strip.

This is useful because pc-bios/meson.build already has a list of all ROM
files, and thus does not need to use wildcards. The problems with
wildcards are mentioned above the definition of the LINKS variable,
but then the recommendation is disattended.
