libbackend.a, for example.  See gcc/

Or you could build it alongside libcpp in libcpp/.  Or in gcc/../libloc.
Either way it would be adding about 6 lines to some and a
couple of gcc/ to point downstream code at header file path
and library path.

Just to clarify, all my comment was intending to address was a build
system POV, I did not intend a design requirement.  Anyway, from a
build-system POV, it seems pointless that the GCC tree has so many
configure scripts most of which do the same thing, but all need to run
separately and so on.  If the directories contain (once-)independent
packages, that is understandable, but otherwise all it produces is build
overhead; in the end, that's not going to help spur development.
I understand the requirement to remain compatible with the src/ tree but
that doesn't mean you can't have one configure script for the bulk of
the target libraries which are not independent projects.

Whereever you decide where this library should end up, if you have
trouble implementing the rules for it, feel free to ping me off-list.
