gmp_4.2.1: fix build for MIPS

The h asm constrain (to extract the high part of a multiplication
result) has not been recognised since gcc 4.4:

  https://gcc.gnu.org/gcc-4.4/changes.html

Drop the MIPS umul_ppmm() implementations which rely on "=h" and fall
back to the older implementations (which use explicit mfhi and mflo
instructions to move the high and low parts of the multiplication
result into their destinations).
