ECL currently uses its own copy of libatomic-ops. For other libraries it
looks around in the operating system, trying to find a suitable version.
Unfortunately libatomic-ops is not so mature and when I tried to do this, I
found that many versions of the library around would not work.

Indeed, if you look at src/aclocal.m4 you will see that the code for
ECL_BOEHM_GC is way more complex than that for ECL_LIBATOMIC_OPS. The
former is looking for preinstalled copies of the GC library, while the
second simply uses the one in ECL.

In order to work with system libraries one would have to first fix this
detection phase. Then one would have to ensure that the GC library is also
installed (GC uses libatomic-ops internally). So while the second step is
up to the user, the first one involves some coding in ECL.
