for ELF modules.
* arch/arm/include/elf.h: Added ARM ELF header file.
* include/elf32.h: Renamed elf.h to elf32.h.
* configs/stm32f4discovery/ostest: Converted to use the new
Kconfig-based configuration system.
* configs/stm32f4discovery/elf and configs/stm32f4discovery/scripts/gnu-elf.ld
Add a configuration for testing the ARM ELF loader.
* binfmt/libelf: Can't use fstat(). NuttX does not yet support it. Damn!
