[Rivet] --no-as-needed only exists for ELF linkers

[Frank Siegert]

While we're at it: for me the yaml-cpp tests failed to build on a
cluster (don't remember exactly why), so I disabled them in the
bootstrap script with the -DYAML_CPP_BUILD_TOOLS=OFF cmake option. If
there are no objections I'd also push this change.

Another issue is the --install-autotools option: It doesn't install
m4, which means that autoconf can't be built if the system m4 is too
old. Again, if there are no objections, I'll add the m4 installation
to --install-autotools.

By the way, in case somebody runs into this as well: I've had an issue
on two completely different clusters now (both possibly SuSE-based
though?) that Rivet wouldn't build with the default libtoolize 2.2.6
because the libtool step simply produced no output:

  make[2]: Entering directory `/.../build/rivet/src/Core'
    CXX    libRivetCore_la-Event.lo
  mv: cannot stat `.deps/libRivetCore_la-Event.Tpo': No such file or directory

Using --install-autotools solved that.

Cheers,
Frank
