The addition of LT_INIT as well as the adjustment of the BUILD_STATIC and addition of the BUILD_SHARED conditionals and their usage to block building of shared objects and adjust the variables for building static libraries is potentially upstream-friendly. The use of a manifest file to keep a list of the objects in each library instead of calling ar is also potentially upstream-friendly. Separate these changes from the macOS-specific hacks.
