guile: fix cross

The upstream patch fixes an include error.

Adding autoreconfHook fixes

       > make -C libguile scmconfig.h
       > make[1]: Entering directory '/build/guile-3.0.10/libguile'
       >  cd .. && /nix/store/xy4jjgw87sbgwylm5kn047d9gkbhsr9x-bash-5.2p37/bin/bash /build/guile-3.0.10/build-aux/missing automake-1.16 --gnu libguile/Makefile

       > WARNING: 'automake-1.16' is missing on your system.
       >          You should only need it if you modified 'Makefile.am' or

       >          The 'automake' program is part of the GNU Automake package:

       >          It also requires GNU Autoconf, GNU m4 and Perl in order to run:
       >          <https://www.gnu.org/software/autoconf>
       >          <https://www.gnu.org/software/m4/>

       > make: *** [Makefile:2615: libguile/scmconfig.h] Error 2

which occurs because we patch a Makefile.am .
