configure: check for program_invocation_name

Browse Source 
For portabiliy, check for program_invocation_name during configure and
define HAVE_PROGRAM_INVOCATION_NAME accordingly. Use of this symbol is
now enclosed with the appropriate #ifdef block.

The symbol program_invocation_name is only used for error message
handling using error(), so it's safe to omit this if it is not
available.
