This change is undoing the makefile change done as part of JDK-8196985.
The only warning that was turning up in libdt_socket code before
JDK-8196985 was done has already been fixed by JDK-8196909. Thus no
warnings need to be fixed.
After removing the above makefile code, I tested by building with the
new toolchain. As a first test I undid the socketTransport.cpp fix from
JDK-8196909 to verify that the new toolchain exposed the warning. Then I
reverted socketTransport.cpp back to tip sources and saw no warnings
with the new toolchain.
