This is the SLES11 system compiler (the last BE SLES).  It's configured
with --with-cpu=3Dpower4 --enable-secureplt --with-long-double-128.  We
do have a patch with power7 enablement (but just recognizing the
command-line option, nothing else).  And yes, lots of more cobbled
up patches (and we never updated to a 4.3.6 baseline either).

That said, it's a bit too short notice to start digging into this
myself and honestly if FSF 4.3.4 and 4.3.6 are not affected I'd not
worry (and instead I'll see to fixing SLE11 instead if the need
arises).  SLE11 also has access to GCC 4.8.5 btw. (just with
binaries inconveniently named gcc-4.8).=
