9fdb93cce0 Make comp.libs use generated templates, too
This allows us to include the component-to-package relation in the
generated kconfig files and make use of that information in the
show-config.sh script.

413f5f6100 Super-H multilib toolchain fixes
1. On SuperH, configuring GCC with explicit variant of the CPU
(like "sh4") limits the default set of multilibs to just that CPU
and requires --with-multilib-list to change. Allow for "unspecified"
variant, so that we can defer to GCC to determine the list.

2. Support toolchains with both endiannesses at the same time.

3. Add a SuperH/newlib sample

4. Add more flags processing for uClibc

ff0a1a3da6 Switch gen-kconfig to new framework
Also:
- Move companion_* to comp_* to match the kconfig symbols
- Replace bootstrap with former gen-versions.sh
- Fold *.in.2 into their respective first parts; this moves common
  options to the end - if it is undesirable, inclusion of *.in
  can be moved where *.in.2 used to be (but that will also move
  version selection after common options).
- Retire addToolVersion.sh (may later replace with a more
  comprehensive script that tries to download the added tarballs,
  copy the patches and try to apply them, and create a version.desc).

bb704f532a Allow --with-cpu/--with-tune for !arm.
The configure error mentioned in the commits that disable
--with-arch/--with-tune when --with-cpu is specified is specific to ARM
builds. For other architectures, it makes sense (hey, it even makes
sense for ARM - read 'info gcc'! - it is just a shortcoming of ARM
build, apparently).

Thus, add an arch setting ARCH_EXCLUSIVE_WITH_CPU (currently, set only
for ARM) that will trigger current behavior. Permit combinations of
--with-arch/cpu/tune for other arches.

88d01dd861 arch: rename the SUPPORT_XXX options
First, 'SUPPORT' should be spelled 'SUPPORTS'.

Second, 'SUPPORT_XXX' really means 'supports --with-xxx', so rename the
affected options accordingly. Update the affected archs to match the new
namings.

d6ab57ffcb arch/arm: ARM supports the softfp convention
ARM compilers can be built for soft float (software only, floats in
core registers), hard float (uses floating point instructions, floats
in FPU registers), or the half-way house softfp (uses floating point
instructions, floats in core registers).

53892de14c config: fix recursive deps
The latest kconfig stuff is more stringent when it comes to validating
the dependency of the symbols. It is no longer possible to have a symbol
depend on itself (such as our construct for arch/cc/libc/... was doing).

Fix our generated-file infrastructure to avoid these situations when the
new kconfig stuff will be merged (in a following changeset).

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
