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.

     3 -= BEGIN original header =-

     4 older verisons of glibc would build dl-sysdep as shared-only and dl-support as

     5 static-only.  alpha hooks in a cache variable via dl-auxv.h.  newer versions of

     6 glibc build dl-sysdep as both shared and static which means we now have symbol

     7 duplication for static builds with dl-sysdep and dl-support.  since dl-sysdep

     8 is both shared/static, there is no point in hooking dl-support anymore, so we

     9 can punt it.
