Either change

  alftest_LDADD = ../src/libalf.a

to

  alftest_LDADD = ../src/libalf.la

This means alftest will be linked against libalf.so or libalf.a
depending on what have been built (the user can disable static
or shared libraries using --disable-static or --disable-shared),
It seems to me this is what you try to avoid.

Or keep the definition for both libraries, and try the
workaround I mentioned:

  libalf_a_CFLAGS = $(AM_CFLAGS)

My limitied testing shows this is enough to suppress the warning.
