        src/libexec/ld.elf_so: tls.c

Log Message:
ld.elf_so: Fix assertions for TLS variant I without _lwp_settcb.

In variant I, the TLS address is always

        (uint8_t *)tcb + sizeof(struct tls_tcb) + obj->tlsoffset.

With _lwp_settcb, (uint8_t *)tcb + sizeof(struct tls_tcb) is aligned,
whereas without it, (uint8_t *)tcb is aligned.  Consequently, with
_lwp_settcb, obj->tlsoffset must also be aligned, whereas without it,
obj->tlsoffset + sizeof(struct tls_tcb) must be aligned -- and hence,
without _lwp_settcb, obj->tlsoffset must be congruent to
-sizeof(struct tls_tcb) modulo the alignment.

No functional change intended for non-DEBUG builds: assertion changes
only here.
