Patch to the lis-1.4.11 autotools build system.
* use autoconf macros to propagate fortran/c link flags instead of custom build ones
* propagate properly CPPFLAGS instead of CFLAGS
* remove custom built linking commands
* use the target check for testing and
* default install only installs the library, not the tests
