libtool.m4: Avoid warning message in test case 30

The test case for deplibs_check_method in tests/demo.at produces a
warning on multiple systems, such as Cygwin and Mingw. To avoid this
warning when using file_magic, '^x86 archive static' is appended for
lt_cv_deplibs_check_method.

* m4/libtool.m4: Append '^x86 archive static' for file_magic in the
lt_cv_deplibs_check_method.
