[PATCH:rendercheck] config: Remove unnecessary calls from configure.ac

[Alan Coopersmith]

AC_PROG_CC & AC_PROG_SED are provided by XORG_DEFAULT_OPTIONS now
PKG_CONFIG_MODULES handles AC_SUBST of the CFLAGS & LIBS variables
XORG_DEFAULT_OPTIONS includes XORG_STRICT_OPTION to set -Werror

Assume systems have xrender.pc now - those building on older systems
can set RC_LIBS="-lXrender -lXext -lX11" plus any -I/-L/-R flags they
need in RC_CFLAGS & RC_LIBS.
