crypto/ipsec_mb: add dependency check for cross build

When cross-compiling for PowerPC on Ubuntu, the x86 IPSec_MB library was getting found by the build system for use in the PPC build. This led to failures at compile time due to the library not being linkable. We can avoid these failures by checking the discovered library for compatibility at configuration time. This needs a version check as it is supported only from version 0.60 of meson onwards.
