While the bad code should be addressed, it appears generally safe, so we should solve it upstream. This patch adds -Wno-unused-but-set-variable to the Cryptlib Makefile, and removes the conditionalization on gcc in the OpenSSL Makefile, as clang now has this argument, and since we don't support building with clang for the final build, it's useful to have clang-based tools working.
