Ping/Repost (Updated 20120127): RFA: Add Epiphany newlib & libgloss port

[Joern Rennecke <amylaar at spamcop dot net>]

While I've been waiting for approval of this port, both the
diff/patch context, and the port itself have changed a bit,
since my posting http://sources.redhat.com/ml/newlib/2011/msg00580.html ,
so I'm reposting an updated version here.

         * COPYING.NEWLIB: Add Adapteva notice.
         * COPYING.LIBGLOSS: Add Adapteva notice.
libgloss:
         * configure.in: Add Epiphany support.
         * configure: Regenerate.
         * epiphany: New directory.
         * libgloss/README: Add Epiphany entry.
newlib:
         * configure.host: Add Epiphany support.
         * libc/include/machine/ieeefp.h: Likewise.
         * libc/include/machine/setjmp.h: Likewise.

I have made the following changes till the last posting (20111110):

- Fixed merge conflict on COPYING.LIBGLOSS due to other port added in the
  meantime.

- switched trap back from syscall to open/read/write trap for backward
  compatibility (while keeping the fixed semantics):
  libgloss:
        * epiphany/open.c (_open): Revert to use asm_open.
        * epiphany/read.c (_read): Revert to use asm_read.
        * epiphany/write.c (_write): Revert to use asm_write.

- Some cleanup in newlib/libc/{sys,machine}/epiphany:
  newlib:
        * libc/machine/epiphany/access.c: Move to libgloss.
        * libc/machine/epiphany/one_cmplsi2.S: Delete.
        * libc/machine/epiphany/Makefile.am (lib_a_SOURCES): Remove access.c
        and one_cmplsi2.S.
        * libc/machine/epiphany/Makefile.in: Regenerate.
        * libc/machine/epiphany/aclocal.m4: Regenerate.
        * libc/machine/epiphany/Makefile.in: Regenerate.
        * libc/machine/epiphany/machine/endian.h: Delete.
        * libc/machine/epiphany/machine/epiphany_config.h: Move to libgloss.
        * libc/machine/epiphany/machine/param.h: Delete.
        * libc/sys/epiphany/isatty.c: Delete (use newlib/posix one).
        * libc/sys/epiphany/mem-layout.c, ___crt0.old.S: Delete.
        * libc/sys/epiphany/Makefile.am (lib_a_sources): Remove isatty.c
        and mem-layout.c .  Add e_printf.c .
        * libc/sys/epiphany/configure.in (AC_CONFIG_SRCDIR): Use e_printf.c.
        * libc/sys/epiphany/configure: Regenerate.
        * libc/sys/epiphany/aclocal.m4: Regenerate.
        * libc/sys/epiphany/Makefile.in: Regenerate.
  libgloss:
        * epiphany/access.c: Moved from newlib.
        * epiphany-config.h: Likewise.
