Regarding this package, apologies I missed it during the initial review :s

This build failure occurs because it goes in a path it should not.
In the Config.in: it is mentionned that mbedtls is prefered to
polarssl [1], hence the select [1] and the dependency in the *.mk [2].
However, the cmake configure flags are not set accordingly to this,
and the defaults may play against us [3].

I would suggest to set the ENABLE_{MBEDTLS,POLARSSL} flags in the *.mk first.
This should prevent from following this case [4], as displayed in the
build log [5].

After this, if the CheckSymbolExists still causes error, we may need
to patch the bctoolbox
cmake code to set/fix the variables used by CheckSymbolExists [6].
