crypto-native: properly deal with broken or outdated toolchains

Avoids crash due to missing symbol, when build system detects toolchain which is not able to produce binaries for all targets we need.... Type: fix Change-Id: I77ee63cb8dca3c9e4e83a6235c60f1439a472444 Signed-off-by: Damjan Marion <damarion@cisco.com>
