Make it easier to configure the name of the QBE binary

While it is already possible to configure the as(1) and ld(1) binary
name through C macros, the QBE binary name is itself currently
hardcoded.  However, for distribution following the functional software
deployment model (e.g., Guix or Nix), it is useful to also make the
name of the QBE binary configurable. This is implemented here through
the addition of a QBEBIN macro.
