### CROSS-COMPILED PLATFORMS ###
# TODO: Introduce three tiers:
#       1. clippy + build crate with --no-default-features only (can be done
#          even on a -none target, should be done on unsupported FP
#          configurations like x86 without SSE)
#       2. clippy + build crate & tests (can be done on a cross -linux target))
#       3. clippy + build crate + run tests (native target)
# TODO: Try to run tests via qemu
# TODO: Add windows, wasi and none coverage
# TODO: Add tests (and, if needed, support) for mips, powerpc64, powerpc64le,
#       s390x and sparc64
