[rfa/toplevel] Conditionalize GDB_TK

[Andrew Cagney <ac131313@redhat.com>]

[-- Attachment #1: Type: text/plain, Size: 322 bytes --]

Hello,

The attatched only adds the tk directories to the gdb dependency list 
when the corresponding tk files are present.  That way `all-gdb' doesn't 
build tk files (except when needed).

ok?
Andrew

PS: Disclaimer, I cut/paste the configure changes.  Perhaphs someone 
able to regenerate configure should commit this?

	* configure.in (GDB_TK): Add tcl directories conditional on
	gdb/gdbtk directory being present.
	* configure: Regenerate.
