If you configure GDB using --prefix=$prefix
--with-system-gdbinit=$prefix/etc/gdbinit, then a GDB installed in
$prefix/bin will load $prefix/etc/gdbinit at startup.  If the tree
is copied to /other/prefix, then GDB will load
/other/prefix/etc/gdbinit.  We use the same algorithm for set
debug-file-directory and set sysroot.

There isn't a standard name.  It's just whatever is given to the
configure option.  Do you think it should have a standard name?
I definitely need the ability to change the name via configure.

Having --help print it out sounds wise to me.
