First attempt at initial evbarm support for cubieboard (compile tested).
Files for allwinner a20/a10 (need to compile stuff in evbarm/cubie)
Don't autogenerate the wrapper that is called from the rump kernel
local syscall entry points.  The wrapper is now so big that it doesn't
get inlined (original intent for having it close to the entry points),
and autogenerating a regular function just loses in flexibility.
RUMPCOMP_USEROBJ -> RUMPOBJ_NORENAME

Widens the implied usage scope of the variable.
Autogenerate rump_syscalls.c into the correct namespace, i.e. it no
longer needs to go through rename in the build.
If RUMP_KERNEL_IS_LIBC is defined, alias the rump kernel syscalls to libc
syscall stub symbol names.  This allows running standalone programs in
OS-less environments such as directly on a Xen DomU backed only by a
libc and a rump kernel.

+ don't rename rump_syscalls.*o
+ support RUMP_KERNEL_IS_LIBC
Very very very prelimnary support for cubieboard 1 & 2 based on the
Allwinner A10 & A20 SoCs.  It links and that's about all it does.
Many drivers are stubs with autoconf glue.
com, ahcisata, sdhc, usb might have a chance of working.
add missing call to ahci_attach at the end of awin_ahci_attach
establish intr handler before calling sdhc_host_found
Typo in comment.
Typo. Bump date.
Fix typos from FreeMiNT's db-1.86 patch.
Add VAR_INTERNAL as a context for variables set by make itself,
which should not override those set by makefiles.
Currently MAKEFILE is the only variable affected.

Add wdog support.  Use wdog to do reset (works for both A10 & A20).
Also create hw.pagesize, makes sysconf(_SC_PAGESIZE) return a more
sensible result.
Import version 458 of "less". Changes since version 444:
* Allow backslash escaping of metacharacters in LESS environment variable
  after the --use-backslash option.
* Don't quit if syntax errors are found in command line options.
* Increase sizes of some internal buffers.
* Fix configure bug with --with-regex=none.
* Fix crash with "stty rows 0".
* Fix display bug when using up/down arrow on the command line.
* Add ESC-F command to keep reading data until a pattern is found.
* Use exit code of LESSOPEN script if LESSOPEN starts with "||".
* When up/down arrow is used on the command line immediately after
  typing text, the next command starting with that text is found.
* Add support for GNU regex.
* Add configure option --with-regex=none and fix compile errors
  when compiling with no regex library.
* Fix possible crashes caused by malformed LESSOPEN or
  LESSCLOSE variables.
* Fix bug highlighting text which is discontiguous in the file
  due to backspace processing.
* Fix bug in displaying status column when scrolling backwards
  with -J and -S in effect.
