Patch to cleanup mystrstr from cplus-dem.c

["Kaveh R. Ghazi" <ghazi at caip dot rutgers dot edu>]

I noticed that cplus-dem.c had its own private strstr function which
seemed unnecessary since libiberty provides one.

Test by bootstrapping on solaris2.7.

Ok to install?

		Thanks,

	* cplus-dem.c (mystrstr): Delete.  All callers changed to use
	strstr instead.
