[debian-mysql] Bug#678252: Please drop gcc-4.4 build dependency now

[Robie Basak]

It has been almost a year since the last comment on this bug. Upstream
still don't appear to support building the embedded ssl library on the
current gcc in a way that works.

Can the decision to build with gcc 4.4 instead of disabling the i386
assembly optimisations now be reconsidered? Perhaps with a view to
making this change when jessie opens?

Note that AFAICT the optimisations are only enabled when __i386__ is
defined, so amd64 has been relying on gcc's optimisation for the
portable C equivalent anyway. I think it's also reasonable to doubt the
usefulness of the assembly that's being used, since it was clearly
designed and compared against an older version of gcc, and using a newer
gcc invalidates any assumptions that the assembly optimisations provide
any performance benefit anyway.

There is a regression risk, but only if the underlying code is broken.
Since the test suite detected the original problem, I think it's
reasonable to consider it to have adequate coverage to manage the risk.

So can we now define TAOCRYPT_DISABLE_X86ASM and drop the use of
gcc-4.4 please?
