[PATCH, applied] abipkgdiff: Emit error when no vmlinux is found in debug package

[Dodji Seketeli <dodji@redhat.com>]

Hello,

When given linux kernel packages to analyze using DWARF, the tool
expects the (uncompressed) vmlinux binary to be found in the debug
info package.

This patch emits an error message when no vmlinux binary is found in
the debug info package in that case.

	* tools/abipkgdiff.cc (compare_prepared_linux_kernel_packages):
	When no vmlinux binary is found in the debug info package, emit an
	error message.
