Add __tls_get_addr() for all targets to crt0. This is not only used on
ARM. In particular, it is used on RISC-V. This helps to adequately
support the GCC libgomp.

In order to enable proper detection of thread-local storage availability
we have to provide some symbols on ARM.

The dummy crt0.c provided by the RTEMS target provides stubs of
symbols which would normally be provided by RTEMS. This patch adds
stubs for posix_memalign() as well as the synchronization methods
prototyped in <sys/lock.h>.
* libc/sys/rtems/sys/queue.h: New file.
* libc/include/sys/signal.h: Reflect renumbering of signals to
fit into 32-bit mask.
* libc/include/sys/unistd.h: Add fdatasync() prototype.
* libc/sys/rtems/crt0.c: Add more symbols which may be implicitly
required. In particular, add the reentrant variants of libc calls.
* libc/sys/rtems/sys/dirent.h: Add scandir() prototype.
* libc/sys/rtems/include/limits.h, libc/sys/rtems/sys/param.h,
libc/sys/rtems/sys/syslimits.h: Update to be in sync with what
constants are defined in each file in the shared versions in
libc/include.
* libc/sys/rtems/crt0.c: Define extra symbols on SH and HP-PA to
autoconf can link programs.
* libc/include/machine/types.h: Explicitly specify signed on
intXX_t types to ensure they are signed.
* libc/sys/rtems/crt0.c (rtems_gxx_mutex_init): Dummy
routine to allow autoconf to determine that building executables
for rtems works.
(rtems_gxx_mutex_lock, rtems_gxx_mutex_unlock): Ditto.
(rtems_gxx_mutex_once): Ditto.
* libc/sys/rtems/crt0.c: Add stubs for functions implicitly
referenced by code generated by gcc 2.8.1.
(a29k): Add stubs for V_SPILL, V_FILL, V_BSD_OS, V_EPI_OS to
satisfy gcc.
