i thought about something like this:

$ cat makefile
SRCS := test.cpp
all: libtest.so libtest.a
libtest.so: $(SRCS:.cpp=.os)
        g++ -shared -o $@ $<
libtest.a: $(SRCS:.cpp=.o)
        ar cr $@ $<
%.os: %.cpp
        g++ -c -fpic -DSHARED -o $@ $<
%.o: %.cpp
        g++ -c -fpic -o $@ $<

but i can't transform it into autotools templates :/
i saw that elfutils does such trick within src/makefile.am.
