[Debian-med-packaging] Bug#966417: vg: FTBFS in sid, with new elfutils

[Gianfranco Costamagna]

Source: vg
Version: 1.25.0+ds-2
Severity: serious

Hello, looks like elfutils dropped one library used by vg:

	# We do not provide a libebl anymore, use libdw instead.
	rm -f debian/tmp/usr/include/elfutils/libebl.h


causing now FTBFS in sid:

I don't know if this patch is enough to make it build correctly, it is still building here
