A motley selection of changes, which ultimately result in a toolchain that produces binaries:

	* Makefile: 
		Change to a two-stage build and build+install clib2 between stages
		Other, associated changes to reflect additional patches etc
	* recipes/files/gcc:
		Contents moved to recipes/files/gcc/gcc
		Various changes to the target configuration to reflect use of clib2
	* recipes/files/ndk:
		Additional header files for the NDK to permit clib2 to build
	* recipes/files/clib2:
		Add sys/wait.h to clib2, and stub out wait(), vfork(), and pipe() for the benefit of libiberty
	* recipes/patches/gcc/(config.host.p,config.gcc.p):
		Renamed to gcc.\1
	* recipes/patches/gcc/libgcc.config.host.p:
		Make libgcc aware of our target triple
	* recipes/patches/binutils/gas.app.c.p:
		Backport a 5-year old fix that prevents the GAS lexer dropping input on the floor
	* recipes/patches/ndk/ndk.inline.intuition.h.p:
		Hack around inline function needing access to a variable from the place it was inlined
	* recipes/patches/clib2/clib2.modern_gcc.p:
		Fix up clib2 to compile with modern GCC
	* recipes/patches/clib2/clib2.include.unistd.h.p:
		Export definitions of vfork() and pipe()
	* recipes/patches/clib2/clib2.include.fcntl.h.p:
		Define FD_CLOEXEC -- the clib2 fcntl() implementation will ignore F_GETFD/F_SETFD anyway
	* recipes/patches/clib2/clib2.GNUmakefile.68k.p:
		Reflect our use of a full target triple in the toolchain settings
		Add stubs.c to build
		Do not attempt to build resident/resident32 library variants

+# Makefile fragment for AmigaOS host

+

+# Each compilation environment (Manx, Dice, GCC, SAS/C, etc) provides its

+# own equivalent of the UNIX /usr/include tree.  For gcc, the standard headers

+# are in /gg/include and system specific headers are in /gg/os-include.

+# Use these paths for fixincludes.

+

+SYSTEM_HEADER_DIR = $(prefix)/include

+

+# Uncomment the following macro to get a resident GCC. We don't do it

+# by default, since we want to support users with mc68000.

+# WARNING!  If you uncomment this, you MUST add the same flags to the

+# libiberty's Makefile (libiberty is now linked into GCC executables).

+

+#RESIDENT = -m68020 -resident32

+

+# Additional host flags that are not used when compiling with GCC_FOR_TARGET,

+# such as when compiling the libgcc* runtime archives. GCC uses stack

+# a lot, and since AmigaOS provides processes with a small, fixed size

+# stack, we have to generate code that will extend it whenever necessary.

+

+XCFLAGS = -mstackextend $(RESIDENT)

+

+# AmigaOS supports "AmigaGuide(R)" hypertext files. For GCC, these are

+# build with a custom "makeinfo".

+

+# Arrange for guides to be build with GCC, in the build directory.
