Stop `configure` and throw an error when `--with-mpfr`,
`--with-mpfr-include` or `--with-mpfr-lib` is passed without an
argument.
If someone by mistake passes any of those options using the option only
or sepparated by a space instead of `=` it currently tries to build it.
Since this syntax is valid in several programs (i.e. those built using
getopt_long), throwing an error might prevent build-time issues.
ChangeLog:
* configure.ac: Validate the value passed for `--with-mpfr`,
`--with-mpfr-include` and `--with-mpfr-lib` to detect 'yes'
(no arguent)
* configure: Regenerate `configure` with `autoreconf-2.69`.
