As Roland noted in 
<https://sourceware.org/ml/libc-alpha/2014-10/msg00369.html>, soft-fp 
subdirectories that are always used are redundant - the files in them can 
be moved one level up, and the entries in Implies removed.

Some new files have the copyright notice as their first line.  The first 
line should be a description of the file (like you have in 
sysdeps/nios2/bits/setjmp.h, for example), with the copyright notice as 
the next line.

Should be GLIBC_2.21 (it's least confusing for Versions entries used only 
on one system to reflect the actual symbol versions on that system, even 
though references to older versions should get automatically adjusted when 
glibc is built).

This was removed from pthreaddef.h on 2014-05-13.  Watch out for any other 
such global changes for which there should be port updates....
