While loading the executable, some platforms (like AVR) need to detect CPU type that executable is built for - and, with this patch, this is enabled by reading the field 'e_flags' of the ELF header of the executable in question. The change expands functionality of the following functions: - load_elf() - load_elf_as() - load_elf_ram() - load_elf_ram_sym() The argument added to these functions is called 'pflags' and is of type 'uint32_t*' (that matches 'pointer to 'elf_word'', 'elf_word' being the type of the field 'e_flags', in both 32-bit and 64-bit variants of ELF header). Callers are allowed to pass NULL as that argument, and in such case no lookup to the field 'e_flags' will happen, and no information will be returned, of course.
