Flex needs m4 to run (see below) and, since the create_wrapper
introduces a bash dependency on target, give the path to m4 binary in
the configure command line.
Snippet from the flex documentation:
"The macro processor m4 must be installed wherever flex is installed.
<...>
m4 is only required at the time you run flex."
