This is only relevant for git builds. For git builds there are a number
of tools we don't explicitly check for such as autoconf itself for
example. The autoconf checks otoh are only relevant for builds from
tarballs. 

It is expected that you need more tools installed when building from
git, and that you know which ones.

That said, libgcrypt really shouldn't use their own macros for this, and
rather just use pkg-config....
