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.

Summary
Fully linked apps take less storage and are efficient to load. This is to enable them for rv-vrit configurations in KERNEL build.
Changes:
Additions:
The ARCH_TEXT_VBASE of knsh32 is set to same as that of 64bit to reuse the apps linker script.
Enabling LIBM makes it convinient for users of toolchains lacking math library
Enableing OSTEST makes it conveinent to run ostest
Impact
Confgurations in kernel build: knsh32. knsh64, ksmp64. knetnsh64. knetnsh64_smp
Testing
Checked with all above configs using kernel build
