As the comment explains, `*Triples[]` lists are discouraged and not
comprehensive anyway (e.g.
aarch64-unknown-linux-gnu/aarch64-unknown-linux-musl/aarch64-amazon-linux do
not work).
Boost incorrectly specifies --target=arm64-pc-linux ("arm64" should not be used
for Linux) and expects to probe "aarch64-linux-gnu". Add this temporary
workaround for the 19.x releases.
