In load_elf_binary(), once the READ_IMPLIES_EXEC flag is set,
the flag is propagated to its child processes, even the elf
files are marked as not requiring executable stack. It may
cause superfluous operations on some arch, e.g.
__sync_icache_dcache on aarch64

In load_elf_binary(), once the READ_IMPLIES_EXEC flag is set,
the flag is propagated to its child processes, even the elf
files are marked as not requiring executable stack. It may
cause superfluous operations on some arch, e.g.
__sync_icache_dcache on aarch64 due to a PROT_READ
