autogen.sh: fix errors with new autotools.

The following errors occurred when running ./autogen.sh :

$ ./autogen.sh
+ aclocal
configure.ac:18: warning: AC_COMPILE_IFELSE was called before AC_USE_SYSTEM_EXTENSIONS
../../lib/autoconf/specific.m4:386: AC_USE_SYSTEM_EXTENSIONS is expanded from...
../../lib/autoconf/specific.m4:332: AC_GNU_SOURCE is expanded from...
configure.ac:18: the top level
configure.ac:18: warning: AC_RUN_IFELSE was called before AC_USE_SYSTEM_EXTENSIONS
configure.ac:19: warning: AC_COMPILE_IFELSE was called before AC_USE_SYSTEM_EXTENSIONS
../../lib/autoconf/specific.m4:459: AC_MINIX is expanded from...
configure.ac:19: the top level
configure.ac:19: warning: AC_RUN_IFELSE was called before AC_USE_SYSTEM_EXTENSIONS

and so on for autoheader and friends.
According to the autotools docs, the proper way to handle this
is to just call AC_USE_SYSTEM_EXTENSIONS.
