Intel Threading Building Blocks (TBB), is a C++ library to help developers
write highly parallelized applications. OpenCV uses it to accelerate some of
it's more heavy weight procedures.

Intel(R) Threading Building Blocks (Intel(R) TBB) lets you
easily write parallel C++ programs that take full advantage
of multicore performance, that are portable, composable and
have future-proof scalability.

# arch is normally set based on uname -m with some conversions. However,
# it is not really used for much:
# - to decide between 32 or 64-bit files (based on '64' in the name)
# - to decide on some arch-specific CFLAGS like -m32, which we don't actually want
# - to set DO_ITT_NOTIFY if it's x86 (32 or 64 bit)
# - to include assembler source, but it only exists for ia64
# The only thing we actually want from the above is the 32/64-bit, and
# DO_ITT_NOTIFY. Therefore, set arch to a fixed value which is unknown to
# the tbb build system, and set DO_ITT_NOTIFY explicitly.
