CMake: Enable -Werror for the -fno-function-sections check
...
If the -fno-function-sections flag isn't recognized, the compiler
emits a warning. This isn't enough to cause the check to fail, so we
enable -Werror as well.

[ASan] Replace the call to "vname" with "WRAP(vname)" in FORMAT_INTERCEPTOR_IMPL
...
It's incorrect to call the function by its name in the interceptor, because that means WRAP(vname) on Linux and REAL(vname) on OSX.
This patch fixes asan/lit_tests/TestCases/printf-3.c on Mac.

tsan: relax check for errno spoiling more
...
We do not detect errno spoiling for SIGTERM,
because some SIGTERM handlers do spoil errno but reraise SIGTERM,
tsan reports false positive in such case.
It's difficult to properly detect this situation (reraise),
because in async signal processing case (when handler is called directly
from rtl_generic_sighandler) we have not yet received the reraised
signal; and it looks too fragile to intercept all ways to reraise a signal.

Adding the ARM RT sources to the CMake files, and enabling some
sanitizers to also build on ARM. This is far from supported or
production quality, but enabling it to build will get us errors
that we can actually fix.
Having said that, the Compiler-RT and the Asan libraries are
know to work on some variations of ARM.
