[dpdk-dev,v3,4/5] mk: use LDLIBS when linking shared libraries
Commit Message
This patch mainly makes use of the LDLIBS variable when linking shared
libraries, setting proper DT_NEEDED entries.
This patch also fixes a few nits like syntax highlighting, the command
string (O_TO_S_CMD) used for linking shared libraries and the displayed
of dependencies when debugging is enable (D).
