LU-1425 build: make Lustre build ready for gcov

gcov requires profiled code to be built with compiler options
-fprofile-arcs -ftest-coverage. To profile all project this
options should be passed during every source file compilation.
This option enable debug logging. No all Lustre parts are ready
for debug logging now.

To patch adds debug librarias where needed and resolve
linking conflicts. Do not influence when no
-fprofile-arcs -ftest-coverage compile options are
passed.
