liblink: fix arm build again

Browse Source 
Another attempt to fix the arm build by moving the include of signal.h
to cmd/lex.c, unless we are building on plan9.

Obviously if we had a plan9/arm builder this would probably not work, but
this is only a temporary measure until the c2go transition is complete.
