[Buildroot] [PATCHv2 buildroot-test 06/11] autobuild-run: add option --make-opts for custom Buildroot options

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

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

In some environments, the Buildroot configuration may need minor
tweaking. For example, in corporate environments behind a firewall,
version control commands like git, svn, ... may actually need wrappers.
Such wrappers could be configured using the corresponding BR2_<CMD>
configuration options.

Since these tweaks are very environment-specific, they should not be
part of the configuration file itself. Otherwise, other people trying to
reproduce the build in another environment will see builds failing due
to other reasons, for example the wrapper not being found.

This commit provides a new configuration option 'make-opts', passable as
argument or in the config file, that accepts a string of make options to
pass to the Buildroot make command. For example:
    --make-opts="BR2_GIT=git-wrapper BR2_svn=svn-wrapper"
