C++20 is mandatory since bump to version 3.2.0 in commit
2f8feb6620 and
e2efb744ce
resulting in the following build failure:
powerpc-linux-g++.br_real: error: unrecognized command line option '-std=c++20'; did you mean '-std=c++2a'?
BR2_TOOLCHAIN_HAS_GCC_BUG_64735 dependency can be dropped as gcc > 7 is
not affected by this bug
Fixes: 2f8feb6620
