mkcheck.in partial patch for AIX

[David Edelsohn <dje at watson dot ibm dot com>]

	The following patch provides support for invoking "size" on AIX
and uses the GCC "-Wl" option more efficiently.

	However, the problem with running mkcheck on AIX is that AIX
linker does not support the "-rpath" option.  It has a "-blibpath:"
option, but the -L$LIB_PATH already suffices.

	Any suggestion on how one would prefer making -rpath optional?
Substitute @rpath@ when building mkcheck?  Test @host_os@ at runtime to
define $RPATH or choose $CXX template?

Thanks, David

	* mkcheck (test_file): Combine -Wl arguments.  Parse "size" on
	AIX.
