In general, such native methods are as portable as the libraries to
which they are interfaced.  If you're calling functions such as those
declared in any standard math.h for example, the most you might require
is a smattering of preprocessor directives in the "C" implementation of
the native method, just as you would with *any* "C" code that needed to
build and run on a variety of platforms.

Java doesn't make "C" portable, but if there libraries that support a
common API on a range of platforms, then using native methods to access
those libraries seems preferable IMHO to another, slower wheel.
