With gnuradio 3.10 boost/filesystem was replaced by std::filesystem. This
feature was introduces with gcc 8 (requirering -lstdc++fs (with
gcc 9 explicit -lstdc++fs is no more explicitely required)).
With gcc < 8 build fails with error:
In file included from /home/br-user/work/instance-0/output-1/host/aarch64_be-buildroot-linux-gnu/sysroot/usr/include/boost/dll/runtime_symbol_info.hpp:11:0,
from /home/br-user/work/instance-0/output-1/build/gnuradio-3.10.4.0/buildroot-build/gnuradio-runtime/lib/constants.cc:16:

#include <filesystem>
^~~~~~~~~~~~
compilation terminated.
This patch add the dependency to gcc >= 8 and removes BR2_TOOLCHAIN_HAS_GCC_BUG_64735
dependency because it is only required for gcc < 7.
Also gcc restriction is required because volk needs a toolchain with a gcc > 7.
Tested with bootlin toolchain 2020.02-2 (gcc 8.3.0)

Changes v2 -> v333
- rewrite commit message
- add dependency to gcc 8 (std::filesystem) instead of 9.3.0 (ubuntu 20.04 LTS)
Changes v1 -> v2:
- remove depends on BR2_TOOLCHAIN_HAS_GCC_BUG_64735
- move gcc dependency to main comment

I reword that slightly.

I also reword that slightly, as it was not explicit enough. (punt)

I was about to actually wait for v333, but decided we need the fix
now... ;-)

Missing comma between "dynamic library" and "gcc >= 8"
Applied to master, thanks.
