ppc-gas: Add '+' and '-' to symbol chars list

[Nick Clifton <nickc at redhat dot com>]

Hi Guys,

  The recent patches to app.c have broken GAS for the PPC.  This is
  because the assembler is now stricter about deciding when it has
  encountered a symbol and the PPC port can have opcodes which include
  the '+' or '-' characters.  (eg "blt-")  This patch fixes this
  problem by adding these characters to the ppc specific symbol list.

  Cheers
        Nick
