Better fix for https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/merge_requests/732 The original issue was that when compiling NetworkManager with slibtool the create-exports-NetworkManager.sh script gave the NetworkManager-all-sym slibtool wrapper script to nm(1) instead of the actual binary. This is because slibtool and GNU libtool do not place the compiled programs in the same location. The original fix was to test both locations, but this is bit of a hack especially since the build system should not be using the .libs directory directly. However with $(LIBTOOL) --mode=execute this is not a problem since both implementations can figure out where the correct binary is. https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/merge_requests/805
