This fixes a compile time warning which is being treated as an error. Older
versions of gcc complain about part of a conditional expression always
evaluating to false because of the size of the operands involved, even when
the entire expression is already known to be false.
* peXXigen.c (_bfd_XXi_swap_sym_out): Another fix for building on
a 342-bit host. This time for older versions of gcc.
