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.
