SERVER-48291 Ensure runtime is dynamically linked in dynamic builds
Prior to this point, a dynamic build might have resulted in some runtime
libraries being statically linked into shared objects and executables in
cases where "shared" runtime libraries were actually linker scripts that
linked static versions. This was the case with the MongoDB toolchain and
some distro toolchains, including those installed as updated compiler
versions in RHEL.
The effect of having runtime libraries statically linked was that
symbols from those libraries would end up scattered over the compiled
objects, increasing object sizes and slowing down server startup. Now,
whenever a dynamic build is selected, the user can choose whether to
create "shim" runtime libraries that wrap the static ones.
The default behavior on Linux is that dynamic builds will detect whether
runtime libraries are linker scripts and create shim libraries if any are
found. On Windows, the default is to always use a dynamic runtime library
with dynamic builds. For other platforms, the prior behavior remains
unchanged.
