Hi,

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

There was testing snafu last time around (wrong branch on build server).
Although only relevant configs are aarch64 and PPC, the series passes
build-many-glibcs for following:

ARCH="aarch64-linux-gnu arm-linux-gnueabi arm-linux-gnueabihf hppa-linux-gnu x86_64-linux-gnu arm-linux-gnueabihf riscv64-linux-gnu-rv64imac-lp64 riscv64-linux-gnu-rv64imafdc-lp64 powerpc-linux-gnu microblaze-linux-gnu nios2-linux-gnu hppa-linux-gnu"

Thx,
-Vineet

  aarch/fpu: use generic sqrt{,f}, fma{,f}, nearbyint{,f} functions
  powerpc/fpu: use generic fma functions
