When for some reason the dependencies of the compiled mbed TLS libaries
(libmbedtls, libmbedcrypto and libmbedx509) are not correct, the configure
script will fail to link against libmbedcrypto and/or libmbedx509.  This
is reported to happen after using 'make install' to install mbedtls.

This patch makes sure the configure tests link to all three.  The build
process itself already did.
