Needs fixed lapack package (#11801) merged first.
With that, this builds, installs and smoke test (`python3 -c "import scipy; help(scipy)"`)
work OK. Previously we where getting missing symbols when attempting scipy builds using meson.
Now we instruct the build to use lapack for LAPACK. At least until we decide to just let openblas
handle BLAS *and* LAPACK.
Solves the issue seen on PR #11536.
* noteshrink: fix missing executable permision.
Forgot to do this when combined the "sed" + "cp" lines I had before.
* scipy: disable recipe to avoid future hangs on the buildmasters.
* python3.8: bulk removal of now obsolete "_python38" packages.
Done via scripting. No functional change intended or expected.
Some manual tweaks will follow.
* python3.8: further manual tweaks after bulk-3.8-removal.
Unlike the previous commit with automated changes,
I've tested builds for *these* recipes in beta4 64 bits.
x86_64 is used as a baseline: the "x86_64" entry, whatever status it has,
is transformed into "all", and then the other entries in ARCHITECTURES
either dropped or rearranged appropriately.
