[proposed PATCH] relocatable-prog: default O_EXEC to O_PATH if available

[Paul Eggert]

* lib/progreloc.c (O_EXEC) [O_PATH]: Default to O_PATH.
This tracks the recent change to fcntl-h.
Perhaps relocatable-prog should depend on fcntl-h instead?

        Linux kernel 2.6.39 introduced O_PATH (see
        <http://lwn.net/Articles/433854/>) and this is a better fallback
