You can't make up EF_* flags this way, they are arch specific, the LSB bit
(but many others too) are already used on many architectures.
E.g.:
elf/mt.h:#define EF_MT_CPU_MRISC 0x00000001 /* default */
elf/sparc.h:#define EF_SPARCV9_PSO 0x1 /* partial store
ordering */
elf/bfin.h:#define EF_BFIN_PIC 0x00000001 /* -fpic */
elf/alpha.h:#define EF_ALPHA_32BIT 0x00000001
elf/mips.h:#define EF_MIPS_NOREORDER 0x00000001
elf/m68k.h:#define EF_M68K_CF_ISA_A_NODIV 0x01 /* ISA A except for div */
elf/sh.h:#define EF_SH1 1
elf/arm.h:#define EF_ARM_RELEXEC 0x01
elf/cris.h:#define EF_CRIS_UNDERSCORE 0x00000001
elf/ia64.h:#define EF_IA_64_TRAPNIL (1 << 0) /* Trap NIL pointer dereferences.
*/
elf/vax.h:#define EF_VAX_NONPIC 0x0001 /* Object contains
non-PIC code */
elf/iq2000.h:#define EF_IQ2000_CPU_IQ2000 0x00000001 /* default */
elf/frv.h:#define EF_FRV_GPR_32 0x00000001 /* -mgpr-32 */
to name just a few.
