SPECS: systemtap: Align optional build options and dependencies

[Jingwiw]

Changes

• Make the avahi and dyninst configure options follow their bconds.

  Both bconds default to off in this spec. Upstream otherwise probes optional support when the option is not explicitly disabled, so pass the matching --without-* flags for the default build.

  Source: systemtap-5.5/configure.ac:477-492

  AC_ARG_WITH([avahi],
    AS_HELP_STRING([--without-avahi],
      [Do not use Avahi even if present]))
  
  AS_IF([test "x$with_avahi" != "xno"], [
    PKG_CHECK_MODULES([avahi], [avahi-client],
      [have_avahi=yes
       AC_DEFINE([HAVE_AVAHI], [1], [Define to 1 if you have the avahi libraries.])
      ], [have_avahi=no])
  ], [have_avahi=no])

  AC_ARG_WITH([dyninst],
    AS_HELP_STRING([--with-dyninst=DIRECTORY],
      [find dyninst headers/libraries in DIRECTORY]))
  
  case "$with_dyninst" in
  no) ;;
  ''|yes) # Try a simple-minded distro search
       DYNINST_CXXFLAGS="-I/usr/include/dyninst"

  esac
  
  if test "$with_dyninst" != "no"; then
    AC_CHECK_HEADERS([dyninst/BPatch_object.h], [
        AC_DEFINE([HAVE_DYNINST],[1],[Define to 1 if Dyninst is enabled])
        have_dyninst=yes
        AC_MSG_NOTICE([dyninst support available])])
  fi

• Use pkgconfig(sqlite3) for the SQLite build dependency.

  Upstream checks SQLite through pkg-config, and the local sqlite devel package provides sqlite3.pc.

  Source: systemtap-5.5/configure.ac:249-262

  AC_ARG_ENABLE([sqlite],
    AS_HELP_STRING([--enable-sqlite], [build with sqlite support]),
    [],
    [enable_sqlite=check])
  
  AS_IF([test "x$enable_sqlite" != xno],
    [PKG_CHECK_MODULES([sqlite3], [sqlite3 > 3.7],
      [AC_DEFINE([HAVE_LIBSQLITE3], [1], [Define to 1 if you have the 'sqlite3' library (-lsqlite3).])],
      [if test "x$enable_sqlite" != xcheck; then
        AC_MSG_FAILURE([--enable-sqlite was given, but test for sqlite > 3.7 failed])
       fi])])

• Drop the duplicate avahi-devel BuildRequires from the server subpackage block.

  The avahi dependency is already expressed once as pkgconfig(avahi-client) under the same %{with avahi} condition, matching the upstream pkg-config check.

  Source: systemtap-5.5/configure.ac:477-487

  AC_ARG_WITH([avahi],
    AS_HELP_STRING([--without-avahi],
      [Do not use Avahi even if present]))
  
  AS_IF([test "x$with_avahi" != "xno"], [
    PKG_CHECK_MODULES([avahi], [avahi-client],
      [have_avahi=yes
       AC_DEFINE([HAVE_AVAHI], [1], [Define to 1 if you have the avahi libraries.])
      ], [have_avahi=no])
  ], [have_avahi=no])
