      It is highly recommended to check the newly built companion libraries.

      Unfortunately, this is a very intensive task, and takes a loooong time.

      Checking the newly built companion libraries is thus disabled by default,

      but it is suggested that you check them at least once on your machine,

      and if they work, disable the check on subsequent builds.

      If you suspect that one (or more) of your companion libraries is the

      cause for incorrectly generated code, you should answer 'Y' here.

      Note however that this will take a really long time. For example,

      building PPL on my machine takes roughly 1'40", while checking it takes

      about 1h40'...

    help

      By default, the companion libraries will be build static. If you want to

      build shared libraries, then you can say 'Y' here, but a wrapper will be

      needed (see: "docs/4 - Building the toolchain.txt", in the section

      "Tools wrapper").

      It is highly recommended that you keep static libraries.

      If your host has a shell, then you should say 'Y' here, to use

      a (very very simple) shell script as wrapper.

      If your host lacks a shell, then you should say 'Y' here, to use
