The attached patch adds the a target specific attribute via the
new target macro TARGET_BEGIN_TRANSACTION_ATTRIBUTE to the
function begin_transaction().  S/390 uses this to set the
soft-float target attribute which is needed to fix a crash with
-m31.

As there seems to be no place in libitm to document internal macros like
USE_HTM_FASTPATH or the new macro, I've put the documentation in a
comment where the macro is used.
