llvm: add dependency on !BR2_TOOLCHAIN_HAS_GCC_BUG_64735
LLVM uses std::shared_future, which until gcc 7.x isn't available on
architectures that don't provide lock-free atomics, see
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64735.
Buildroot already has a BR2_TOOLCHAIN_HAS_GCC_BUG_64735 option to
handle such a case, so simply add this new dependency to LLVM. It will
make sure LLVM doesn't get built on ARMv5 platforms using a gcc older
than 7.x.
