> 	ld: genassym.o: RRS text relocation at 0x2a60 for "mcount"

This error is the result of not specifying `-pg' when linking `genassym'.
Actually the Makefile should be tweaked to not compile genassym.c with `-pg'
in the first place.

This is another case of (mild) `gcc -Wall' braindamage. If it cared to inspect
the code after processing of the `asm' lines, it would note that `_mcount'
does get defined..
