It actually does, until I add an @AC_SUBST@ into the target name.
In this example, I use a nonstandard library name, but it doesn't
matter -- it's still duplicated if it's called "address@hidden@.a"

# configure.ac
AC_INIT(fakelib,0.0)

RANLIB=:
AC_SUBST(RANLIB)
AM_INIT_AUTOMAKE(fakelib,0.0)

AC_SUBST(SUBST)

# Makefile.am
noinst_LIBRARIES = address@hidden@.lib

address@hidden@_lib_SOURCES = abra.c kadabra.c

# then we override the target rule:
address@hidden@.lib: Makefile $(address@hidden@_lib_OBJECTS) 
$(address@hidden@_lib_DEPENDENCIES)
        @echo here we do some custom stuff, instead of invoking the linker
