You're mixing up GNU make-specific constructs (ifeq, and others, see
<http://www.gnu.org/software/make/manual/html_node/Conditionals.html>)
together with Automake.  Automake only understands most of POSIX
make features, and is only able to ignore some GNU make extensions.

OTOH, Automake has some extra features, such as Automake conditionals:
<http://sources.redhat.com/automake/automake.html#Conditionals>

You need to choose to either use Automake, and thus give up some GNU
make specific functionality, or use GNU make, and give up Automake
(i.e., write a Makefile, not Makefile.am; or write a Makefile.in which
is then treated by e.g., a configure script generated by autoconf).

Hope that helps.

Cheers,
Ralf
