Hi,
We have automake packaged, but it's not compatible with older autoconf
versions so autoconf is not very usable at this point.
```
Ekaitz@tuxedo ~/projects/nlnet/gcc/libstdc++-v3 (riscv)$ guix shell
automake autoconf@2.64
Ekaitz@tuxedo ~/projects/nlnet/gcc/libstdc++-v3 (riscv) [env]$
autoreconf -vif
autoreconf: Entering directory `.'
autoreconf: configure.ac: not using Gettext
autoreconf: running: aclocal --force -I . -I .. -I ../config

autoreconf: aclocal failed with exit status: 63
```
Is this only my thing?
