x86: Fix objdump version check in chkobjdump.awk for different formats.

Different version of objdump says its version in different way;

GNU objdump 2.16.1

or

GNU objdump version 2.19.51.0.14-1.fc11 20090722

This patch uses the first argument which starts with a number
as version string.

Changes in v2:
 - Remove unneeded increment.
