[Buildroot] [PATCHv2 buildroot-test 10/11] autobuild-run: save config.log files for failed package

[Thomas De Schampheleire <patrickdepinguin@gmail.com>]

From: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com>

This patch will save all config.log files of the failed package in the
result tarball, to help problem analysis. This is typically useful for
autotools packages, although the added logic does not check that
explicitly (i.e. any failing package that has a config.log file in the
output directory will see this file saved).

The saving of config.log files happens recursively, the directory
structure is preserved in the result directory.

-#   failed builds when the failure occurs on an autotools package.
-#
 # - Instead of excluding all configurations that have
 #   BR2_PACKAGE_CLASSPATH=y, improve the script to detect whether the
 #   necessary host machine requirements are there to build classpath.
