Should I backport this? I suppose yes.

An observation:
grass70/configure.in" line 1632
[CAIRO_HAS_XRENDER_SURFACE=1],[CAIRO_HAS_XRENDER_SURFACE=])
AC_SUBST(CAIRO_HAS_XRENDER)
LOC_CHECK_FUNC(cairo_xlib_surface_get_xrender_format,,,,,$CAIROLIB,
[CAIRO_HAS_XRENDER_SURFACE=1],[CAIRO_HAS_XRENDER_SURFACE=])

while
grass64/configure.in" line 1670
[CAIRO_HAS_XRENDER=1],[CAIRO_HAS_XRENDER=0])
AC_SUBST(CAIRO_HAS_XRENDER)

-> note the =0 in 6.4 while in 7 there is only = for the 0 case.

This looks inconsistent to me.
