# cryptography and cffi publish no 32-bit ARM wheels, so armv7
# compiles both from source: cffi needs the libffi headers, and
# cryptography's Rust extension needs rust/cargo plus the OpenSSL
# headers found via pkgconfig (DK-A2). All of it is removed again
# by the trailing `apk del`, so the final image size is unchanged.
