Minor patch to libf2c/configure.in

[Rainer Orth <ro at TechFak dot Uni-Bielefeld dot DE>]

make bootstrap of egcs-2.92.32 19981222 on Ultrix V4.3 fails in libf2c:

checking f2c integer type...
configure: error: Can't determine type for f2c integer; config.log may help.

config.log shows (on IRIX 6.2 where the same problem exists, but doesn't
hurt since /bin/sh's builtin test isn't as broken as the Ultrix one;
confusingly the problem doesn't exist at all on Digital UNIX V4.0B):

The following patch fixes this:

	* configure.in: Need to search toplevel include dir for ansidecl.h
	and libiberty.h needed by config.h and system.h, respectively.
