[Mono-dev] [PATCH] Minor MIPS changes to mono/mono/mini

[Mark Mason]

Hello all,

Included below are patches to mono/mono/mini to begin adding support for
MIPS to the Mono JIT.  Primarily, this includes minor header file changes,
Makefile support for MIPS, and making print_ins() non-static for better
verbose support.

MIPS-specific files, and substantive MIPS-specific changes to shared
files will follow in later patches.  I just wanted to get the trivial
one out of the way first as a test balloon.

Tested by building svn tip + these changes for x86, and running 'make
check' in mono/mono/mini.

Thanks in advance,
Mark
