Richard Sandiford - June 3, 2013, 7:16 p.m.
Some (but not all) 64-bit MIPS configurations were setting target_cpu_default
to MASK_64BIT|MASK_FLOAT64.  This has been redundant for a long time.
The masks are now derived from the ABI and ISA settings, and also aren't
tested directly in preprocessor conditions (such as those used when setting
up the default multilibs).

This patch removes them.  Tested on mips64-elf and applied.

	* config.gcc (mipsisa64sr71k-*-elf*, mipsisa64sb1-*-elf*)
	(mipsisa64sb1el-*-elf*, mips64-*-elf*, mips64el-*-elf*)
	(mips64orion-*-elf*, mips64orionel-*-elf*): Remove
	target_cpu_default setting.
