LibCore: Add support for double on argparse

Browse source 
Code is pretty trivial. If someone needs "float" support, a copy-paste
will be in place.

Build system was confused between math.h from rootfs, and toolchain. I
fixed the problem caused by `math.h` by locally using the builtin
`isnan()` from the compiler. It's ugly - but works. I am looking for
other alternatives.
