Well, I am not sure if I understand correctly.
Is this a request to upgrade binutils to binutils-2.19 for all targets
or a request to upgrade the powerpc-binutils?
The former is unlikely to happen, and if only after extensive testing.
The latter might worth consideration, should there be agreement on this
by all active powerpc-rtems4.9 users.
Joel, do you recall any major binutils-2.18/binutils-2.19
incompatibilities rsp. have they been backported to rtems-4.9?
IIRC, there had been some, but the details have escaped me.

Applying this patch would change the ABI of the powerpc toolchain.
I.e. unless we agree upon making an exception to our release policies
("No API nor ABI changes"), there is hardly any possibility to make this
Powerpc users, please speak up !!!!
