Thanks, but this was not sufficiently tested it seems: on my Fedora
system with gcc 9.x, BR2_HOST_GCC_VERSION was still 8, and therefore
BR2_HOST_GCC_AT_LEAST_9 was not "y". This is because the main Buildroot
Makefile HOSTCC_MAX_VERSION variable needs to be updated as well.

I fixed that up and applied to master. Thanks!

Best regards,

Thomas

Sorry for that.

I was looking at [1] at the same time (that is why I noticed this symbol was
missing).
