[builds/unix] Handle 'librsvg' for demo programs. * builds/unix/configure.raw: Check for 'librsvg'. (LIB_CLOCK_GETTIME): Don't call `AC_SUBST` on this but on... (FT_DEMO_CFLAGS, FT_DEMO_LDFLAGS): ... these two new variables. * builds/unix/unix-cc.in (LIB_CLOCK_GETTIME): Replaced by... (FT_DEMO_CFLAGS, FT_DEMO_LDFLAGS): ... these two new variables.
