Update the TA makefiles to support C++ (file extension: .cpp).
This allows the use of C++ in TA and libraries, with limitations (see
below). I consider this work experimental because it was only tested
with simple cases in xtest, introducing the required changes and
addressing issues one after another. Therefore, some features may be
missing for more complex use cases (additional relocation types or
runtime support...).
Tested with the arm-linux-gnueabihf- and aarch64-linux-gnu- toolchains
(GCC 8.3).
Limitations:
- Clang is not supported at the moment
- Exception handling: shared libraries cannot throw, catch or propagate
exceptions. Doing so would require linking the libraries and the main
program with the shared libgcc [1] which is not straightforward due
to the many dependencies on the GNU libc. Exceptions *can* be used in
the main program however, as well as in static libraries directly
linked with the main program.
- ldelf stack unwinding does not support C++ frames so crash/panic
dumps will likely be truncated when they involve C++ code.
