Since $(AS) is the assembler, passing it a list of preprocessor include
flags doesn't make much sense. The files aren't preprocessed which means
`#include` lines aren't respected, and while it would affect `.include`
usage, we never use that, and it's extremely unlikely to change. Plus,
it's extremely unlikely we'd have .s files in common places to include vs
contained entirely within a specific arch dir, and at that point, it can
be included directly (with no flags), or the arch can add the unique set
of include paths that it needs for itself.
The newlib & libgloss dirs are already generated using autoconf-2.69.
To avoid merging new code and/or accidental regeneration using diff
versions, leverage config/override.m4 to pin to 2.69 exactly. This
matches what gcc/binutils/gdb are already doing.
The README file already says to use autoconf-2.69.
To accomplish this, it's just as simple as adding -I flags to the
top-level config/ dir when running aclocal. This is because the
override.m4 file overrides AC_INIT to first require the specific
autoconf version before calling the real AC_INIT.
In order to transition to automake, we have to use hardcoded paths in
the AC_CONFIG_AUX_DIR macro call (since automake evaluates the path
itself, and doesn't expand vars), so simplify all the calls here.
Regenerate the files using automake-1.15 & autoconf-2.69 to match the
binutils/gdb/gcc projects. Ran:
libgloss $ find -name configure.ac -printf '%h\n' | while read d; do
(cd $d; export WANT_AUTOCONF=2.69 WANT_AUTOMAKE=1.15;
aclocal-1.15 -I.. && autoconf-2.69); done
* spu/sbrk.c: Use the current stack pointer value rather than the
maximum available memory to determine the amount of heap space
left. Without this change calling sbrk() can allocate space that
is currently in use on the stack.

it (it is the same as syscall_write_t).
* spu/stat.c: Move struct syscall_stat_t to here.
* spu/write.c: Move struct syscall_write_t to here.
* spu/close.c: Pass the address of the first and only argument to
__send_to_ppe rather than using an automatic variable and a
special struct.
* spu/dup.c: Ditto.
* spu/unlink.c: Ditto.
* spu/syscalls.c: Change __send_to_ppe to return the result stored
in stored in slot 0 of the data, rather than have each assisted
