NP, I'm one of the few who still do shared tree builds and to do that 
you need the copies of libiberty and include from binutils/gdb (well, 
it's mostly the extended headers).

It does make me wonder why, in the days of git, we aren't using git 
modules in both tools now for libiberty and include, then we wouldn't 
have sync problems.
