This is a minority viewpoint, IMO.  We could argue for months about
what a "script" is, but that wouldn't help much.  Makefiles are often
referred to as "build scripts", and I don't think many folks would
argue that they are *not* scripts.

You are going into nitpicking arguments about semantics and
definitions at this point, which is not particularly useful: you are
wasting everyone's time, including your own.

The intent of the GPL requirement is clear: the build system in a
distributed source tree licensed under the GPL must be GPL (or
compatible with the GPL).  That is, the mechanism used to build GPL
code is an intrinsic part of a GPL licensed work, and so cannot be
licensed in an incompatible manner.
