REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1089
When building CryptoPkg with Clang, blow error may result
* /usr/lib/llvm-3.8/lib/clang/3.8.0/include/stdatomic.h:105:17: error:
unknown type name 'wchar_t'
Since the C native atomics are C11 feature we can explicitly
use C99 to work around it.
add -std=c99 to avoid it
* openssl/crypto/conf/conf_sap.c:71:12: error: variable 'ret' is
uninitialized
when used here [-Werror,-Wuninitialized]
Suppress warnings in OpenSSL so we don't break the build with -Werror.
add -Wno-error=uninitialized to disalbe this warning
