One-line tweak for old-dejagnu.exp

[Zack Weinberg]

The check for a compiler crash greps specifically for 
"Internal compiler error" and will therefore miss gcc.c's
"Internal error: segmentation fault".

I don't believe this problem is triggered anywhere in the
current sources, but it is triggered by some experimental
patches in my tree.

Applied under obvious bugfix rule.

	* lib/old-dejagnu.exp: Check for both "Internal compiler error"
	and "Internal error".
