New math package: m4rie-20200125
Requirement for #19090.

I get the following error and I don't know how to change a file during the configuration.

```
Makefile.am:5: error: Libtool library used but 'LIBTOOL' is undefined
Makefile.am:5:   The usual way to define 'LIBTOOL' is to add 'LT_INIT'
Makefile.am:5:   to 'configure.ac' and run 'aclocal' and 'autoconf' again.
Makefile.am:5:   If 'LT_INIT' is in 'configure.ac', make sure
Makefile.am:5:   its definition is in aclocal's search path.
Makefile.am: installing './depcomp'
parallel-tests: installing './test-driver'
autoreconf: automake failed with exit status: 1
=> ERROR: m4rie-20200115_1: pre_configure: 'autoreconf --install' exited with 1
=> ERROR:   in pre_configure() at srcpkgs/m4rie/template:25
```
