Commit 10a66a8e42 ("Remove <libc-tsd.h>") removed the TLS initial-exec
(IE) model attribute from the __libc_tsd_CTYPE_* thread variable declarations
and definitions. Commit a894f04d87 ("Optimize __libc_tsd_* thread
variable access") restored it on declarations.
Restore the TLS initial-exec model attribute on __libc_tsd_CTYPE_* thread
variable definitions.
This resolves test tst-locale1 failure on s390 32-bit, when using a
GNU linker without the fix from GNU binutils commit aefebe82dc89
("IBM zSystems: Fix offset relative to static TLS").
