Please give more details of the failures you see (with this patch, as 
opposed to the "[PATCH] math: Don't declare __XXX math functions [BZ 
#32418]" one).  It seems rather odd for a change adding !IS_IN 
(testsuite_internal) conditionals to break the build of glibc itself.  
(And this patch is only changing non-installed files, it's nothing to do 
with what's in installed headers.)
