Re: [PATCH] binfmt_elf_fdpic: only honour the first PT_INTERP

Hi,

Sorry if I messed this up. First time replying via git.

I ran Fable on all of the "nommu files" and it found the issue this
commit fixes and the above issue,
I sent a patch (co-written with fable) and we proved this is an actual
issue on nommu via a reproducer tested on a real system.
