abab3f15b5 config/arch: re-organise architecture-specific options 
Move the arch-specific options to the second-part of
the generated files, so they appear after the generic
options, but before the optimisations.

43ca5b4095 config: add support for a second part of the generated choices 
Some components have configuration options that can depend on
generic options, so they should go below those.

uClibc for example:
- has its own options (wchar...)
- uses the generic options (threads...)
- if linuxthreads chosen, offers two impls

So we need to be able to split the components options in 2,
one part that is above the generic options, and one part that
ends up below the generic options.

d276ce2a4f config: fix style issues when source-ing files 
Always enclose the sourced file between double-quotes (purely for
consistency; enclosing or not are both allowed by the kconfig language).

Add new hidden config knobs that architectures can select to

Yann E. MORIN"
45747a6453 Merge the uClinux/noMMU stuff back to /trunk: 
- merge Linux and uClinux back to a single kernel
- add ARCH_USE_MMU and acquainted config options that
  architectures can auto-select
- make binutils and elf2flt two "Binary utilities" that
  go in a single common sub-{menu,directory} structure

799672a641 Introduce a new EXPERIMENTAL feature: BARE_METAL. 
This should ultimately llow to build bare-metal compilers, for targets that have no kernel and no C library.
Move the C library build script to their own sub-directory; introduce an empty build script for bare-metal.
Move the compiler build script to its own sub-directory.
Move the kernel build script to its own sub-directory; introduce an empty build script for bare-metal.
Update the ARM target tuples to enable bare-metal targets.
Add two ARM bare-metal samples.
Add latest Linux kernel versions.

ef0f400c26 Introduce four new ARCH specific variables that CT_DoArchValues can set if they want: 
- CT_ARCH_CC_CORE_EXTRA_CONFIG
  - CT_ARCH_CC_EXTRA_CONFIG
  - CT_ARCH_TARGET_CLFAGS
  - CT_ARCH_TARGET_LDFLAGS
This will hopefully enable architectures to specify specific flags.
PowerPC will need them to introduce SPE (coming RSN).

7131764f9c Remove any reference to libfloat. That has gone once and for all. 
Rationale:
Most of the time, soft-float problems are caused by this sucker of gcc:
it has support for soft float for all of the targets I've tried so far,
but does not activate this code until you dwelve into half a dozen of
files to make it accept to build and link the support code...

So, yes: gcc has soft-float support. And again, yes: gcc is a sucker.
