I think derivative or not is not the question here, but the GPL
explicitly demands that the build system is available under
GPL-compatible changes.
from Section 2 of the GPL:
# b) You must cause any work that you distribute or publish, that in
# whole or in part contains or is derived from the Program or any
# part thereof, to be licensed as a whole at no charge to all third
# parties under the terms of this License.
from Section 3 of the GPLL:
# Accompany it with the complete corresponding machine-readable
# source code, which must be distributed under the terms of Sections
# 1 and 2 above on a medium [...]
# For an executable work, complete source
# code means all the source code for all modules it contains, plus any
# associated interface definition files, plus the scripts used to
# control compilation and installation of the executable.
"scripts used to control compilation" is clearly what we currently
refer to as "build system".
Hochachtungsvoll,
