patch for building xfs-cmds/attr on 64 bit platforms

[Timothy Shimmin <tes@xxxxxxx>]

Hi there,

In November last year, Jan Derfinak, supplied a patch for 
building/installing xfs-cmds on amd64
but Christoph had problems with "uname --hardware -platform" on some 64 
bit machines.
(http://oss.sgi.com/archives/linux-xfs/2004-11/msg00115.html)

Looking around I decided to adopt a solution from gettext which has a 
config macro which
looks at $CC -print-search-dirs for lib64 to make the decision.
I've attached a patch just for xfs-cmds/attr to this email.
If this works for people on various 64 bit platforms,
then I'll do likewise for the other xfs related userspace libraries.

Thanks muchly,
Tim.
