[sparc64] security/polarssl build fix

Two small things to fix. -Werror chokes on

/usr/obj/ports/mbedtls-2.28.0/mbedtls-mbedtls-2.28.0/library/timing.c:141:2:
error: #warning OpenBSD does not allow access to tick register using software version instead [-Werror=cpp]
#warning OpenBSD does not allow access to tick register using software version instead
^~~~~~~

and then there's a for( size_t i; ...) that isn't accepted by gcc4
outside of C99 mode.

Use the usual fixes. All tests pass.

PS: setting -DUNSAFE_BUILD=ON instead of growing the CMakeLists.txt
patch doesn't work since gcc doesn't understand -Werror=cpp.
