Synopsys ARCv3 ISA includes 32-bit ARC HS5x targets and
64-bit ARC HS6x targets. Both CPU families are placed
in "arc64" subdirectories as it done for GCC port.
Target name arc64 is used for historical reasons and
Synopsys ARCv3 baremetal toolchains contain multilib
configurations both for 32-bit and 64-bit families.
arc32 target name is reserved for 32-bit ARC HS5x
targets in case of non-multilib 32-bit builds.
Note that libgloss libraries for ARCv3 are compatible with
libgloss for ARCv1/2. Thus, Makefile.inc for libgloss uses
sources from libgloss/arc directory except crtX.S files.

- The PRU newlib port is supposed to implement case #2 as described in
newlib/libc/include/reent.h . Thus drop the defining of
MISSING_SYSCALL_NAMES.
- libgloss/configure: Regenerate.
- libgloss/libnosys/acinclude.m4: Do not define
MISSING_SYSCALL_NAMES for pru.

These subdirs have unique configure scripts to do some compiler tests.
The checks should work for all targets, so hoist them up to the top
libgloss dir. This should allow us to delete these subdir configure
scripts.
It means the top-level gains autoheader support, but that's fine.
It wasn't exporting any defines previously (i.e. -D into CPPFLAGS),
and all of the defines it now exports are only used by code in the
libnosys subdir which was expecting to have a config.h.
