Those symbols are not satisfied by any code or dependency of libm. As result calling cprojf function will always crash on Genode. This crash can be turned into link time error by adding --no-undefined to LD_OPT. This patch provides the missing symbols by including isninf.c in libm build. Fixes #4299
