run as a 32 bit support library for an amd64 kernel. 32 bit consumers of
libthr have zero chance of running on an amd64 kernel since we don't
implement the i386_set_ldt() family of functions. Note that this commit
doesn't make it actually work, it just removes one more obstacle.
can't use the i386_set_ldt() family of routines, because they are not
implemented. Instead, use the recently exposed direct access sysarch
routines for setting what %fs and %gs point to.
Use this for the i386 TLS _set_tp() routine, but only when compiling to
run as a 32 bit support binary for amd64 kernels.
syslog(3) if we are a priveleged program (sshd, su, etc.).
- Make syslogd open an additional socket /var/run/logpriv, with 0600
permissions.
- In libc, try to use this socket.
- Do not loop forever if we are using this socket (partial backout of 1.31)

the GPT partition on i386 and adm64 as type=gpt, subtype=0 and with the
sname set to the UUID. This prevents sysinstall from bombing out. This
also makes sure the GPT partition shows up in sysinstall so as to avoid
accidental "clobberage".

deallocation code in rtld seems no lock protection or it is broken,
under stress testing, memory is corrupted.
