[oe] [PATCH][meta-oe][V2] php: add a vardeps for configure on sysconfdir

[rongqing.li at windriver.com]

From: Roy Li <rongqing.li at windriver.com>

Installing target file will fail when sstate is used, since native php is used
to install these files, makefile rule is in php-5.5.24/pear/Makefile.frag
|--------------------------------------
|install-pear-installer: $(SAPI_CLI_PATH)
|	@$(PHP_NATIVE_DIR)/php $(PEAR_INSTALL_FLAGS) $(builddir)/install-pear-nozlib.phar \
|-d "$(peardir)" -b "$(bindir)" ${PEAR_PREFIX} ${PEAR_SUFFIX}
|--------------------------------------
But if sstate is used, native php from sstate has some obsolete path, lead to
that config file is installed into obsolete path. 

Other packages fixed this kinds of issue by calling create_wrapper, like
in openssl, rpm; but test show it does not work for php.

only php depends on php-native, so add a vardeps for configure on sysconfdir
to force php-native to build always.
