common:
* The new, experimental thread-local memory allocation had
inadvertently been left enabled for gmake builds in 0.3.3

TESTING/MATGEN) has been fixed.

input sizes where the overhead of multithreading exceeds
any possible gains
* CSWAP and ZSWAP have been limited to a single thread
except on ARMV8 or ThunderX hardware with sizable input.

x86_64:
* Retired some older targets of DYNAMIC_ARCH builds to a
new option DYNAMIC_OLDER, this affects PENRYN,DUNNINGTON,

be supported via the slower PRESCOTT kernels when this option
is not set)

DYNAMIC_ARCH) allows to specify the list of x86_64 targets to
include. Any target not on the list will be supported by
the Sandybridge or Nehalem kernels if available, or by Prescott.
