New errno.h entry?

[Yves Pelletieri <ypelletier@cmc.doe.ca>]

Hello all

While porting the Empire unix client to MiNT,  I came across an error
descriptor that was not in the MiNTlibs... namely: EAGAIN.

So I just took a look at errno.h and added an entry where it seemed fit.
If there are reasons why the error number should not be 92, let me
know.
