[RFA] make mips64_transfers_32bit_regs_p configurable

[fnf at ninemoons dot com]

I'm working on a port where it makes sense to have the default setting
for mips64_transfers_32bit_regs_p be settable in a target
configuration file.  Would the mips maintainer please review this
patch and either apply it or let me know how it needs fixing.  Thanks.

	* mips-tdep.c (mips64_transfers_32bit_regs_p): Allow default for
	this to be set by the config.
	(MIPS64_TRANSFERS_32BIT_REGS_P): If not defined, use 0.
