fix parallel build issues with APFS/HFS+/ext2/3 in netlib-lapack
The problem is that OpenBLAS sets the LAPACKE_LIB and the TMGLIB to the same object and uses the `ar` feature to update the archive file. If the underlying filesystem does not have sub-second timestamp resolution and the system is fast enough (or `ccache` is used), the timestamp of the builds which should be added to the previously generated archive is the same as the archive file itself and therefore `make` does not update the archive. Since OpenBLAS takes care to not run the different targets updating the archive in parallel, the easiest solution is to declare the respective targets `.PHONY`, forcing `make` to always update them. fixes #1682
