This kind of questions is going to be an FAQ ;)

Makefile.am:
..
if HWPLATFORM_LC1
MORE = -L../lcp_objects -ldiaglcpobj
endif
if HWPLATFORM_SUP1
MORE = -L../smp_objects -ldiagsmpobj
endif

diag_LDADD = ... $(MORE)
..

Alternatively you could compose these flags from inside of your
configure.ac and let it be passed to the Makefile by AC_SUBST:

configure.ac:
[..]
if test ..; then
# LC1
MORE= ...
else
# SUP1
MORE= ...
fi

AC_SUBST(MORE)
[..]

Makefile.am:
diag_LDADD = ... @MORE@

I'd use the second alternative, because it is more in the spirit of
autoconf (setup anything based upon conclusions from feature-checks).
