Add libdl for TAs Adds basic support for dlopen(), dlsym() and dlclose(). The flags passed to dlopen() must be (RTLD_NOW | RTLD_GLOBAL | RTLD_NODELETE); other values are not supported at the moment.

ldelf, libutee: add minimal Thread Local Storage support Preparing for C++ support in TAs. Adds enough runtime Thread Local Storage (TLS) support for the GNU C++ compilers (arm-linux-gnueabihf-g++, aarch64-linux-gnu-g++) to work with OP-TEE. That is: - A Thread Control Block, - The __tls_get_addr() and dl_iterate_phdr() functions. Note that __tls_get_addr() is an ABI helper so it has no prototype in a user-accessible header file. dl_iterate_phdr() however is defined in <link.h> and may be used in a TA. The file lib/libutee/include/link.h is borrowed from Android's Bionic [1] with minor changes (added the required #include statement and named the function parameters). A similar <link.h> header is provided by other C libraries such as GNU libc, musl and FreeBSD/NetBSD/OpenBSD.
