[FYI] Minor gdb/Makefile.in cleanups

[Tom Tromey]

This removes an IMO not very useful comment in gdb/Makefile.in about
"alloca".  It also removes INFOFILES, which I think probably has not
been useful since whenever the manual was moved into a subdirectory.

	* Makefile.in: Remove "alloca" comment.
