avr-ld does not recognise at94k

[Ville Voipio]

avr-ld version 2.11 does not recognize the switch -mmcu=at94k.

The linker gives an error message indicating that emulation mode "avr5" is
missing. The linker does link correctly to -mmcu=avrmega161, which is
another avr5-family processor, and the library files are available.

There seems to be a way to avoid the problem. The linker seems to perform
correctly if the target is given as avrmega161 but the startup code is
given as "crtat94k.o".

The worst consequence of the problem is that it is impossible to use the
automation offered by avr-gcc, and the compiling and linking have to be
performed as different operations.
