Subject: [PATCH] configure: fix parsing issue with more than one value per
option
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2016061

configure: fix parsing issue with more than one value per option
With commit a9c3d70d902a ("configure: add options ability") users are no
more able to provide wrong command lines like:
$ ./configure --include_dir foo bar
The script simply bails out when user provides more than one value for a
single option. However, in doing so, it breaks backward compatibility with
some packaging system, which expects unknown options to be ignored.
Commit a3272b93725a ("configure: restore backward compatibility") fix this
issue, but makes it possible again for users to provide wrong command lines
such as the one above.
This fixes the issue simply ignoring autoconf-like options such as
'--opt=value'.
