Hello,

This series was motivated by some CI failures we saw in OpenBMC on our
ppc64le build machines, driven by the python3-cryptography dependency of
the tpm2-pkcs11 package, pulled in via packagegroup-security-tpm2.

I previously sent an initial, wildly insufficient attempt that fixed the
immediate error of using a bad architecture name in the snapshot
download URLs:

https://lore.kernel.org/openembedded-core/20220218054315.169005-1-andrew@aj.id.au/

Khem was on the money with his query, and pulling that thread led
to this unwieldy series. Together these patches (plus another for
meta-openembedded to fix CARGO_BUILD_TARGET) result in a successful
`bitbake python3-cryptography` targetting an ARMv7 machine (an ASPEED
AST2600 BMC SoC) on ppc64le and x86-64.

Please treat the patches with suspicion, I really just slashed my way
through it all until the build didn't fail, then tried to clean the
result up into a series that might be reviewable. Hence RFC.

Anyway, please take a look!

Andrew
