it's possible: when you're building the library, instead of specifying
the C library to link as -lpcre, specify the static lib directly, eg:
    ocamlopt -a -o pcre.cmxa ... -cclib /usr/lib/libpcre.a
and then link your application as usual (and add the -verbose flag to
ocamlopt to check what's going on exactly).

If you don't want to re-build the caml pcre library, you could also
use the -noautolink flag I think:
    ocamlopt -o my_app pcre.cmxa -noautolink -cclib /usr/lib/libpcre.a
my_app.cmx ...
