Since uclibc-ng is the default libc in Buildroot, enabling riscv64 change implicitly the libc used by qemu_riscv64_virt_defconfig. Before this patch qemu_riscv64_virt_defconfig used glibc, after it use uclibc-ng (like other defconfig does). Maybe add a commit before this one enabling explicitly glibc in qemu_riscv64_virt_defconfig, then add this commit and finally a third commit switching qemu_riscv64_virt_defconfig from glibc to uclibc-ng. Anyway it's good to see new architecture supported in uclibc-ng.
