[Patches] Revert some differences from glibc

["Joseph S. Myers" <joseph@xxxxxxxxxxxxxxxx>]

Examining diffs between glibc and EGLIBC showed some differences that no 
longer serve a purpose, if they ever did; I've applied this patch to 
remove them.  cross-zic is no longer of use now timezone data isn't 
installed by glibc; configure now tests elsewhere for nm, and that GNU awk 
is in use; the crt*.S rework means __i686 undefinitions / redefinitions 
are no longer needed.
