Bug#947236: llvm-toolchain-9: Tries to build polly documentation when polly is disabled

[John Paul Adrian Glaubitz]

Source: llvm-toolchain-9
Version: 1:9.0.1-2
Severity: normal
User: debian-powerpc at lists.debian.org
Usertags: powerpc

Hello!

On powerpc, the build fails because llvm-toolchain-9 tries to build the documentation
for polly even though polly is disabled:

cd /<<PKGBUILDDIR>>/build-llvm/tools/clang/stage2-bins/tools/clang/tools/extra/docs && /usr/bin/sphinx-build -b html -d /<<PKGBUILDDIR>>/build-llvm/tools/clang/stage2-bins/tools/clang/tools/extra/docs/_doctrees-clang-tools-html -q /<<PKGBUILDDIR>>/clang-tools-extra/docs /<<PKGBUILDDIR>>/build-llvm/tools/clang/stage2-bins/tools/clang/tools/extra/docs/html
/usr/lib/python3/dist-packages/sphinx/builders/html.py:138: RemovedInSphinx20Warning: builder.css_files is deprecated. Please use app.add_stylesheet() instead.

Does it actually make sense to build documentation in the binary-arch target? Shouldn't
this be moved to the binary-indep target so the documentation lands in the arch:all
package?

Thanks,
Adrian
