toolchain/Config.in: add BR2_TOOLCHAIN_HAS_GCC_BUG_121567

This will be needed to work around a GCC bug affecting python3. The
bug is reported at
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=121567.

This bug affects GCC at least since 6.x, but we couldn't test earlier
versions, so we simply assume all GCC versions are affected. Even GCC
15.x is still affected, as reported to upstream GCC.
