f91f1c0fb8 [BZ #15022] Correct global-scope dlopen issues in static executables. 
This change creates a link map in static executables to serve as the
global search list for dlopen.  It fixes a problem with the inability
to access the global symbol object and a crash on an attempt to map a
DSO into the global scope.  Some code that has become dead after the
addition of this link map is removed too and test cases are provided.

17db6e8d6b [BZ #10283] localedef: align fixed maps to SHMLBA 
Many Linux arches require fixed mmaps to be aligned higher than pagesize,
so use the SHMLBA define as it represents this quantity exactly.

This fixes spurious errors seen on those arches like:
cannot map archive header: Invalid argument

61dd6208fb New API to set default thread attributes 
This patch introduces two new convenience functions to set the default
thread attributes used for creating threads.  This allows a programmer
to set the default thread attributes just once in a process and then
run pthread_create without additional attributes.

I have small patch for new Intel Silvermont machines.

I checked this on my machine and see that strcpy, ... unaligned
versions are faster than ssse3 versions.
