[commit] Switch hppa64 to multi-arch-partial

[Andrew Cagney <ac131313 at redhat dot com>]

Hello,

The attached switches hppa64 to multi-arch partial.  Building a 64 bit 
debugger using:

	CC="cc +DA2.0W -Ae" configure hppa64-hp-hpux11.00

Builds.  The GDB can even set breakpoints vis:

$ ./gdb ./gdb

I don't think the symbol problem is being caused by multi-arch.
