New macro AC_FC_MODULE_EXTENSION: Fortran 90 module extension.
* lib/autoconf/fortran.m4 (AC_FC_MODULE_EXTENSION): New macro,
rewritten from the AX_F90_MODULE_EXTENSION macro from the
Autoconf Macro Archive by Luc Maisonobe and Alexander Pletzer.
* doc/autoconf.texi (Fortran Compiler): Document it.
* tests/local.at (_AT_CHECK_ENV): Do not complain about
FC_MODEXT setting.
* NEWS, THANKS: Update.
