Harmen Stoppels 3ed4263ad7 DT_NEEDED for shared builds in makefile
The makefile build specifies -L. -lmbedx509 -lmbedcrypto flags first,
and only then object files referencing symbols from those libraries.

In this order the linker will not add the linked libraries to the
DT_NEEDED section because they are not referenced yet (at least that
happens for me on ubuntu 20.04 with the default gnu compiler tools).

By first specifying the object files and then the linked libraries, we
do end up with libmbedx509 and libmbedcrypto in the DT_NEEDED sections.

This way running dlopen(...) on libmedtls.so just works.

Note that the CMake build does this by default.
