[OE-core] [PATCH 0/1] RFC - Enable GCC 5.3 transactional support

[Mark Hatle]

GCC has supported -fgnu-tm, libitm and __transaction_stomic [and related] since
GCC 4.7.  OE however has not activated the functionality.  I'm starting to see some
data base programs (and RPM) that can make use of the functionality to create better
thread-safe code.

This includes a patch to GCC.  I've verified it is working based on the recent rpm
5.4.16 work.  It also should not expand the size of the target unless the user adds
the libitm support to their system.

I'd recommend we consider this patch to enable the additional support.

The following changes since commit 8b7ff912ccaadfc0f355642f2a9f99c334a61253:

  db: remove the NO_UPDATE_REASON and replace it a comment about RPM (2016-02-29 22:13:42 -0600)
