ldso/libdl: Also include dl-tls.h for for !SHARED.

On MIPS, several relocations that were original only resolved by the
dynamic linker were reused as static relocations.  Consequently the
macros TLS_DTPREL_VALUE and TLS_TPREL_VALUE defined in
libpthread/nptl/sysdeps/mips/dl-tls.h need to be available even for
!SHARED.

Relevant: http://www.linux-mips.org/wiki/NPTL#History

Original patch by Vincent Wen <wenvincent@gmail.com>:
http://lists.uclibc.org/pipermail/uclibc/2013-April/047707.html

When build statically linked applications for MIPS platform,
sometimes the linker fails with following errors:
undefined reference to TLS_DTPREL_VALUE
undefined reference to TLS_TPREL_VALUE
The include of dl-tls.h is only in code guarded by SHARED,
Removing the SHARED compilation option to cover static link too.
