This is backwards from how things usually work; is this a requirement?
Generally speaking, the closer to the source code the marking is, the higher
priority it is. e.g., an attribute overrides a pragma which overrides a command
line flag. So I think it'd be natural for a user to expect
`stack_protector_ignore` attribute to override the command line flag. WDYT?
