Log:
Detect when libsrtp cannot be linked in a shared library

The libsrtp build system currently does not produce a shared library
or a static library compiled with -fPIC, so on 64-bit systems it is
possible that we will get a compile error if libsrtp is installed and
res_srtp is selected in menuselect.

This patch attempts to detect this situation and provide the user with
instructions to work around the problem.
