[PATCH] powerpc: Fix check-localplt from 99303f3871

[Adhemerval Zanella]

The misc/hash.c uses floating-point operations and powerpc softfp
also exports the same libgcc symbols, which creates extra PLT calls.
Use the same hack from divdi3-symbol-hacks.h to route such calls
internally.

Checked with build/check for powerpc-linux-gnu-soft.
