Fix the following -Werror warning from clang 3.5.0, while building cddl/lib/libctf:

In file included from cddl/contrib/opensolaris/common/ctf/ctf_create.c:31:
In file included from sys/cddl/contrib/opensolaris/uts/common/sys/sysmacros.h:34:
sys/cddl/contrib/opensolaris/uts/common/sys/isa_defs.h:334:9: warning: '_ILP32' macro redefined [-Wmacro-redefined]
#define _ILP32
        ^
<built-in>:26:9: note: previous definition is here
#define _ILP32 1
        ^
1 warning generated.

This is because clang 3.5.0 started predefining _ILP32 and __ILP32__ for
the i386 arch.  (Earlier versions already predefined _LP64 and __LP64__
for the x86_64 arch.)

Fix the following -Werror warning from clang 3.5.0, while building
lib/libngatm:

The idea is to remove any ambiguity by replacing the macro with an
equivalent static inline function.
