Applied to master, thanks.

Note however, that the issue is really about gcc >= 7.5. We do not have
such a symbol, and we do not want to add it. So, adding the dependency
on host gcc >= 7 is not strictly correct, because it allows for gcc 7.4
and below... And gcc 7.5 was the last release in the 7.x branch. It is
probably a safe bet to require 8.x now.

Adam has sent a patch doing that; I already asked him on IRC to rebase
on master now that I applied your patch.

Regards,
Yann E. MORIN.
