package/boost: boost-thread needs a toolchain without bug 64735

boost-thread needs std::current_exception since version 1.71.0 and
https://github.com/boostorg/exception/commit/386f5507cb8ec99c03ca535bea4f8bd61e0de910

std::current_exception depends on !BR2_TOOLCHAIN_HAS_GCC_BUG_64735 as a
result, gnuradio fails to build on:

         else if (auto* p=std::current_exception().__cxa_exception_type())
                          ^
So add this dependency on boost-thread, boost-log and gnuradio (the only
reverse dependencies of boost-thread that does not already depends on
!BR2_TOOLCHAIN_HAS_GCC_BUG_64735)

Finally, add this dependency on gqrx as it is a reverse dependency of
gnuradio
