Not true on some platforms.  Interix is notable and will *break* if a shlib
is installed without +x.

Classically, *all* shared objects, dlopen()ed or not, required execute
permission, because that permission was used to govern whether mmap()ed
pages could be marked executable.  This warning is therefore quite correct.

IIRC, there was a movement recently to bring that constraint (optionally)
back to NetBSD for precisely that purpose:  text-execute restriction.
