Are we talking about the same things? All these ports arlready did
it conditionally on _UC_TLSBASE:

src/sys/arch/arm/arm/sig_machdep.c:
        if ((flags & _UC_TLSBASE) != 0)
                lwp_setprivate(l, (void *)(uintptr_t)mcp->_mc_tlsbase);

src/sys/arch/mips/mips/cpu_subr.c:
        /* Restore the private thread context */
        if (flags & _UC_TLSBASE) {
                lwp_setprivate(l, (void *)(intptr_t)mcp->_mc_tlsbase);
        }

src/sys/arch/vax/vax/machdep.c:
        if (flags & _UC_TLSBASE) {
                void *tlsbase; 
 
                error = copyin((void *)tf->tf_sp, &tlsbase, sizeof(tlsbase));
                if (error) {
                        return error;
                }
                lwp_setprivate(l, tlsbase);
                tf->tf_sp += sizeof(tlsbase);
        }

src/sys/arch/m68k/m68k/sig_machdep.c:
        if ((flags & _UC_TLSBASE) != 0)
                lwp_setprivate(l, (void *)(uintptr_t)mcp->_mc_tlsbase);
