[PATCH] Fixes for a small number of compiler warnings

Hi there,
When building Binutils with FreeBSD's stock compiler (Clang 3.4.1), I
observe a small number of compiler warnings that get turned into
errors. More specifically:
- cpu_flags_set(): this function doesn't seem to be used.
- gld*_before_allocation(): we attempt to initialize a variable with
itself. It looks like there's no need to initialize this variable, as
its use is always guarded by ehdr_start.
Attached is a patch that fixes both these compiler warnings.
