MIPS: math-emu: Move various objects into an ar library.
ieee754d.o contains only debug code and dp_sqrt.o and sp_sqrt.o contain
code which for MIPS I/II/III systems we don't want to link. Again the
savings can be considerable for some systems:
$ mips-linux-size --totals ieee754d.o dp_sqrt.o sp_sqrt.o
