(a) The different choice of time_t is specific to x32 *with the Linux 
kernel* and so should go in a Linux-specific sysdeps directory.

(b) For installed headers, a single header needs to handle all the 
different multilibs that can use a single compiler.  That is, just as 
sysdeps/unix/sysv/linux/x86/bits/typesizes.h handles all of i386, x86_64 
and x32, so these headers also need to be in 
sysdeps/unix/sysv/linux/x86/bits/ and contain conditionals for x32 
(defined __x86_64__ && defined __ILP32__) to determine the definitions to 
use.  You can't use e.g. x32-specific directories for installed headers, 
only for other implementation files.
