localplt data for Power soft-float

["Joseph S. Myers" <joseph at codesourcery dot com>]

This patch adds localplt data for Power soft-float.

The mechanism for doing so requires a distinct ABI name to be defined, 
which in turn requires a copy of the C++ types data (identical to that for 
hard float).

One fix is made to reduce the number of symbols listed in the localplt 
data.  It's possible that the list of soft-fp symbols may vary depending 
on details of the compiler version.  As for the others, the abort call 
comes from the use of soft-fp in libgcc's long double support, various 
mathematical function calls arise from things not being inlined for 
soft-float (and the use of -fno-builtin-fabsl in 
sysdeps/powerpc/nofpu/Makefile), and fegetround is also called by some 
libm functions and inlined only for hard float.
