Use 4.9 mips64el toolchain for both 64- and 32-bit builds.
Tell ld when 32-bit links are required.
Override 4.9's changed defaults for mips floating point
register use, to get same assembler rules as 4.8 and earlier.
Also: drop unused soft-fp build targets, cleanout redundant
compiler options, and remove extraneous Android.mk file.
