MIPS endianness patch

[Gavin Romig-Koch]

I've just commited the following.

                                       -gavin...

This adds a new macro to the MIPS targets that specifies the default
multilib option for endianness.  This patch then uses that macro to
fix a bug in the tx39el configuration where the driver believed the
default libraries were big endian.


	* config/mips/mips.h (MULTILIB_ENDIAN_DEFAULT) : New macro.
	(MULTILIB_ENDIAN_DEFAULT) : Use the new macro.
	* config/mips/elf64.h (MULTILIB_DEFAULTS) : Use the new macro.
	* config/mips/r3900.h (MULTILIB_DEFAULTS) : Use the new macro.
