Is there a reason to use isaexec on SPARC? There's no 32-bit kernel
anymore, so the 32-bit binary will not be used by isaexec, but could only
invoked manually. Unless the 64-bit GDB has trouble debugging 32-bit
programs, there's no reason to ship the 32-bit version on SPARC at all.

but this should be stated explicitly and the isaexec step omitted to avoid
the unnecessary overhead.

I think those should be listed in this case as well. What about symlinks
for info and man pages?

Rather than list all files and directories in SUNWgdb, it would be better
to list the exported (and imported) interfaces and their stability. In
particular, what about readline support? Will it be included?
