Paul Mundt 2504075d38 sh: mach-systemh: Kill off dead board.
This code has been untouched since it was merged many years ago, and has
severely bitrotted since, suggesting that the board has no real users
left. Notice of intent to remove has been sent out over the last few
years, with no takers. Kill it off.

In the case where we are stuck with a compiler that has been uselessly

restricted to a particular ISA, a favourite default of newer GCCs when

extensive multilib targets are not provided, ensure we get the best fit

regarding FP generation. This is intentionally stupid (albeit many

orders of magnitude less than GCC's default behaviour), as anything

with a large number of multilib targets better have been built

correctly for the target in mind.

At this point, anything goes.

-Wa,-isa= tuning implies -Wa,-dsp for the versions of binutils that

support it, while -Wa,-dsp by itself limits the range of usable opcodes

on certain CPU subtypes. Try the ISA variant first, and if that fails,

fall back on -Wa,-dsp for the old binutils versions. Even without DSP

opcodes, we always want the best ISA tuning the version of binutils

will provide.

CPU header paths

These are ordered by optimization level. A CPU family that is a subset

of another (ie, SH-2A / SH-2), is picked up first, with increasing

levels of genericness if nothing more suitable is situated in the

hierarchy.

As an example, in order of preference, SH-2A > SH-2 > common definitions.
