realpath also exists on other systems, though the options you used 
are not portable.

How about going with your patch, just without the -es options?  (I 
verified that this works on FreeBSD, for example.)

That gives me major headache. :-)

Let's go with your patch for trunk and the GCC 6 branch.  Beyond
those, I would not care, though if you feel about it a bit more
strongly, no objection.

Note, there is a second hunk in the patch you posted (cf. the
attached) that makes sense, but will need to be added to the
ChangeLog.
