Fix TLS allocation and loading in !SHARED case
For ARCH where shared lib are not supported:
- SHARED is not set (!SHARED is true)
- __ARCH_HAS_NO_LDSO__ is set
so code inside #if !defined __ARCH_HAS_NO_LDSO__ && !defined SHARED
is compiled-out.
But without a call do _dl_aux_init(), _dl_phdr stays NULL and
__libc_setup_tls won't be able to allocate memory for the in-executable TLS
and also won't be able to load the initimage from ELF TLS segment.
This results in segfault when doing things like "errno = 0" like
in tst-cancel15.c for instance in uClibc-ng testsuite.
