I think the problem here is , during waf configure process, it first checks installed rtems bsp, but the CFLAGS provided doesn't have -lm flag. but I try to manually edit RTEMS_TOOLCHAIN/lib/pkgconfig/arm-rtems5-tms570lc4357_launchxl.pc, but the configure still doesn't have the CFLAGS loaded from this pkgconfig ( during waf configure, it haved loaded it )
