Yanfeng Liu a9372627d8 risc-v/rv-virt: use fully linked apps for kernel build
Fully linked apps take less storage and are efficient to load. This
is to enable them for rv-vrit configurations in KERNEL build.

Changes:

- arch/risc-v/Kconfig       select BINFMT_ELF_EXECUTABLE for QEMU-RV
- boards/risc-v/qemu-rv/rv-virt/configs
  - knsh32/defconfig        enable ELF_EXECUTABLE, LIBM, OSTEST
  - knsh64/defconfig        enable ELF_EXECUTABLE, LIBM, OSTEST
  - ksmp64/defconfig        enable ELF_EXECUTABLE, LIBM, OSTEST
  - knetnsh64/defconfig     enable ELF_EXECUTABLE, LIBM, OSTEST
  - knetnsh64_smp/defconfig enable ELF_EXECUTABLE, LIBM, OSTEST

Additions:
- boards/risc-v/qemu-rv/rv-virt/scripts/
  - gnu-elf.ld              apps linker script

The ARCH_TEXT_VBASE of knsh32 is set to same as that of 64bit to reuse
the apps linker script.
