[OE-core] [PATCH] insane: handle recursive configures when checking for unknown configure options

[Ross Burton]

Some recipes have configure scripts that recursively call other configure
scripts (e.g. dropbear).  These multiple-line matches were not being handled
correctly, so iterate over every matching line instead of assuming only one line
was found.
