[v3,0/4] Enable generic math code for more arches

  Hi,

This was suggested by Adhemerval Zanella as part of ARC hard float
review.

changes since v2:
  - Add new defines (0) to s390 too as suggested by Stephan
  - Handle USE_FMA_BUILTIN in both sysdeps/ieee754/{dbl-64,ldbl-128}/s_fma.c
  - Add diff output for all arches build tested

build-glibc-many tested for following
  aarch64-linux-gnu
  arm-linux-gnueabi
  arm-linux-gnueabihf
  hppa-linux-gnu
  x86_64-linux-gnu
  riscv64-linux-gnu-rv64imac-lp64
  riscv64-linux-gnu-rv64imafdc-lp64
  powerpc-linux-gnu
  microblaze-linux-gnu
  nios2-linux-gnu
  hppa-linux-gnu
  s390x-linux-gnu"

Thx,
-Vineet
