scripts/functions: test for decompressors before use

./configure does check for the presence of gz and bzip2, so we can
safely use them in the build scripts.

On the other hand, more recent formats (eg. XZ) are not yet widely
available, and we do not want, and can't, force the user to install
them as a pre-requisite.

So, build up a list of allowed tarball formats based on the available
decompressors. For no, this is a static list, but the upcoming XZ
support will conditionnaly add to this list.

      Say 'y' here, unless you don't want shared libraries.

      You might not want shared libraries if you're building for a target that
yann@1502
    38
      don't support it (maybe some nommu targets, for example, or bare metal).
