File xen.tools-firmware-pass-EXTRAVERSION-to-seabios-build.patch of Package xen

Subject: tools/firmware: pass EXTRAVERSION to seabios build

Having a fixed version string in the seabios binary is cumbersome:
- it is required to write something to '.version' in the toplevel
  directory of seabios-dir-remove.
- it is required to pass EXTRAVERSION= to make because its toplevel
  Makefile does not take EXTRAVERSION from environment

Adjust the code to create a '.version' file with fixed content.
Adjust the code to pass EXTRAVERSION down to make.
