[PATCH][SH] Fix a few architecture variant settings

[Andrew Stubbs]

Hi,

I recently noticed that GDB claims that the 'fake' SH architecture 
"sh2a-or-sh4" does not have FP registers:

(gdb) show architecture
The target architecture is set automatically (currently sh2a-or-sh4)
(gdb) info float
No floating-point info available for this processor.

This is not true - sh2a-or-sh4 is the intersection between the SH-2A and 
SH-4 architectures, both of which have double-precision FP. This 
assembler/linker automatically select this architecture when FP 
instructions are used, but they cannot tell which architecture was 
intended (the two architectures are incompatible in some ways, but there 
are a set of programs that will run on both).

When examining the source I also noticed that a number of architectures 
have no specific 'regs' command variant configured (causing them to 
default to the most basic variant).

This patch solves both problem problems.

OK?

Andrew
