ocamlyices2: use --without-gmp-embedded by default

After giving it some thoughts, the need for having a self-contained libyices.a
(which would only need -lyices, no -lgmp needed) in ocamlyices2 is pointless
as 'zarith' will still need '-lgmp' anyway.

The Makefile will still put libgmp.a and libyices.a inside src/ so that
the static version of gmp is used (with -L.) instead of the shared version.

Rationale: disabling the partial linking fixes the build on Arch Linux, which
(I re-tested on a docker image) cannot accept partial linking with -lgmp when
only libgmp.so is available. Here is the failing command:

    ld -r *.o -lgmp -o libyices.o
