defined (FOO) -> defined FOO

[Paul Eggert]

I installed this minor stylistic change:

2006-01-23  Paul Eggert  <address@hidden>

        * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Prefer "defined
        FOO" to "defined (FOO)".
        * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Likewise.
        * lib/autoconf/headers.m4 (AC_HEADER_STAT): Likewise.
        * lib/autoconf/specific.m4 (AC_XENIX_DIR): Likewise.
        * tests/tools.at (ifnames): Likewise.
