Subject: [PATCH] Parameterize the program name

Instead of calling $(basename $0) in multiple places to compute the
program name, set a global PROGNAME variable with this value.

I'm doing this because I created a nixpkgs package for tk and, due to
the way nixpkgs works, the installed binary ends up being a wrapper
with a weird name (.tk-wrapped).  This wrapper name shouldn't be
shown to the user.  By unifying the program name under a single global
variable, I can make the nixpkgs package build replace this line with
a hardcoded program name.
