tweaks from me:
- add a comment to the Makefile patch explaining that it fixes linking
on ld.bfd arches
- pass X11BASE in via the environment rather than patching configure.in,
allowing use of upstream's standard configure script rather than regenerating
The last update removed some includes needed to build qrouter with
base-gcc, provide a different fix that requires less patches, and
apply it to all compilers like it used to be (hints by sthen@).
OK sthen@, kmos@ and Alessandro De Laurenzis (maintainer) on gcc-only fix
design.

Qrouter is a tool to generate metal layers and vias to physically
connect together a netlist in a VLSI fabrication technology. It
is a maze router, otherwise known as an "over-the-cell" router or
"sea-of-gates" router. That is, unlike a channel router, it begins with
a description of placed standard cells, usually packed together at
minimum spacing, and places metal routes over the standard cells.
Qrouter uses the open standard LEF and DEF formats as file input and
output. It takes the cell definitions from a LEF file, and analyzes
the geometry for each cell to determine contact points and route
obstructions. It then reads the cell placement, pin placement, and
netlist from a DEF file, performs the detailed route, and writes an
annotated DEF file as output.
