[dpdk-dev] [PATCH v2 02/12] mk: remove multi-target install

Thu Dec 3 06:01:59 CET 2015


The multi-target install create some subdirectories with the target name
which is not standard for a "make install" procedure.

The uninstall procedure cannot be applied properly (without removing
all files in a directory). It would need to pre-compute paths.
As it is a packaging issue, it is removed from the build system capabilities.
