ah, you are right! we even still have the "libatomic_ops" external!

i just didn't notice because it's only used on non-x86 platforms.

yes, Tamás needs to write some makefiles after all :)

that will be a UnpackedTarball, possibly a ExternalProject (unless it's
one of those "header-only" things), possibly a Library (if it doesn't
build in any sane way with MSVC), probably a ExternalPackage (unless
it's completely statically linked).

but we can keep it simple stick to the (above mentioned) comment and not
support the scenario with system tommath and bundled firebird, either
bundle both or take both from system.  that means we likely don't need
to detect "tommath" in configure, unless it's exposed somehow by
firebird's public headers.
