+Subject: [PATCH] Call apxs with correct prefix
+
+php uses apache's apxs script from staging directory to install libphp
+dynamic library and update /etc/apache2/httpd.conf in the staging and target
+directories. Here is the full command line:
+"apxs -S LIBEXECDIR='$(INSTALL_ROOT)/usr/modules'
+ -S SYSCONFDIR='$(INSTALL_ROOT)/etc/apache2' -i -a -n php7"
+This does not work for target directory as apxs sets the full path of the
+library and not the relative one. Indeed, apxs is smart enough to substitute
+away the prefix specified in $(STAGING_DIR)/usr/build/config_vars.mk so
+httpd.conf will only be correct in the staging directory.
+To fix this, add -S PREFIX='$(INSTALL_ROOT)/usr' to apxs call in configure
