This patch logic resovles a linking issue with ncurses in the mesa
package. This appears to be a recurring problem that was identified in
the mesa gitlab issues here:
https://gitlab.freedesktop.org/mesa/mesa/-/issues/2843
Using `_llvm_method = 'auto'` is broken. This patch replaces that with
`_llvm_method = 'config-tool'`, which is a hack, but makes it possible
to build.
I have commented on the closed issue (2843), referencing the original
author of the bug, and one of the mesa developers, so perhaps they will
fix the problem.
