# 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.
