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.
