CONFIG: adjust make scripts for darwin

- handling of dead links (find -L -delete unsupported)

- remove ignore case flag on 's/../../i' used in have_scotch script.
  It is unneeded and not tolerated by Darwin's sed.

- avoid embedded comments in EXE_INC (Make/options files), which do
  not work well with the OSX LLVM cpp.
  It strips out the comments but also removes the continuation char.

STYLE: adjust notes about paraview library locations

@alexey - stumbled across this. Looks like a typo to me, or is this actually something that works for darwin?

Unfortunately can't tell from the commit message, but the lack of special comment here makes me think typo.

Thanks, /mark

[Alexey Matveichev]

-delete is incompatible with following symlinks. Here is a quote from man (bold is mine):

Delete found files and/or directories. Always returns true. This executes from the current working directory as find recurses down the tree. It will not attempt to delete a filename with a / character in its pathname relative to . for security reasons. Depth-first traversal processing is implied by this option. Following symlinks is incompatible with this option.

[Mark OLESEN]

Thanks - what about the trailing \+ instead of a \; - looks weird

[Alexey Matveichev]

With \+ we have single rm invocation. I.e. with \; exec is expanded into

rm result1
rm result2
...

with \+ it is expanded into

rm result1 result2 ...

See, for example, https://stackoverflow.com/questions/6085156/using-semicolon-vs-plus-with-exec-in-find.

[Mark OLESEN]

Perfect! I guess I could have checked SO myself, but there are seemingly many darwin-specific things that I get pretty nervous.

I'll add a small comment (in develop) for a personal reminder.

Thanks!!!
