Comment(by ryandesign@…):

 I meant to add these notes:

 Replying to [ticket:25257 ryandesign@…]:
 > This patch fixes libmcs.dylib's install_name

 This patch assumes the patch from #25256 has already been applied.

 >  * [https://webkeks.org/hg/buildsys/rev/8bd55aa046bd Include the library
 version in the resulting .dylib.]

 This seems like a good idea to add.

 >  * [https://webkeks.org/hg/buildsys/rev/d8962c219f95 No need for
 -flat_namespace and -undefined dynamic_lookup is better.]

 I don't totally understand these changes but I suppose they may as well be
 added.
