Maybe we need to have some kind of convention of a specific string to
include in the comment on such hacks, in order to more easily grep?

Like:

# Workaround gcc-prXYZ

or

# Workaround binutils-prXYZ

This way, we can grep for "gcc-pr" and "binutils-pr" and easily check
the status of those PRs.

For sure, I'm not claiming we should keep things as-is. It's good to
add temporary hacks, but it's also good to think about how we can at
some point remove those hacks.

Best regards,

Thomas
