Fix v850 libgloss for c99/gcc-14

So the prior patch for sysnecv850 was in newlib.  This time we're fixing 
v850 bits in libgloss.


Like other patches submitted recently, this converts implicit ints to 
explicit ints, adds a missing prototype and header includes.

OK for the trunk?

Hi Jeff, please feel free to check in such similar patches in other
libgloss platforms.  Are there any more?
I ask because it makes sense to hold off the snapshot until you are done.

We're about done with the trivial ones.  And some of the stuff needs 
cleanup in my local tree before submitting to be consistent (ex, don't 
explicitly prototype something when we can just #include the right header).

Point being, I think things will be broken a bit longer with gcc-14, but 
that's still months from release, so I don't think that's a major problem.

I'd lean towards making your snapshot whenever is convenient for you and 
the project rather than waiting for everything to be working with gcc-14.
