We can enable uclibc for RISC-V 64 bit now that it has been
bumped from v1.0.32 to v1.0.34.
Uclibc has had basic support for RISC-V 64 bit since v1.0.31, but
shared library and TLS/NPTL support has only been available since
v1.0.33.
This update has been tested using qemu_riscv64_virt_defconfig and
the Buildroot host QEMU.

Changes v1 -> v2:
- use BR2_RISCV_64 instead of (BR2_riscv && BR2_ARCH_IS_64)
