Subject: [PATCH] [Driver] Temporarily probe aarch64-linux-gnu GCC installation
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.
