scripts: fix dumping config

libelf has been moved to being a companion library, now.

config: hide entries when in backend mode

This implies hidding entries for:
- binutils libraries
- dmalloc
- duma
- native gdb
- ltrace
- strace
- sstrip

kconfig: silence a warning about undefined env variable

When using an environment variable to set a config entry,
don'twarn if it is not defined. Update doc accordingly.

config: prepare for build-system backend

When acting as a backend for a build-system, we should not build
any application that runs on the target, that is:
- no native gdb
- no companion libraries
- no binutils libraries
- no debug tools (save for gdbserver)
- ...

Here, we simply prepare the (hidden) config option that will detect
that we are acting as a back-end.

Update doc accordingly.

kernel/linux: add latest versions 2.6.32.10 and 2.6.33.1

debug/gdb: fix building the native tic

The native 'tic' will _always_ be run on the build
machine, so no need to handle canadian/native/...

libc/glibc: add patch to fix binutils version check

Older glibces were not ready to handle binutils >=2.20.
Fix that, and the forseeable future.

debug/ltrace: properly fix building for powerpc

ltrace uses ppc, whereas crosstool-NG use powerpc.
Fix that by passing the correct value to HOST when calling configure.

debug/ltrace: fix building on x86

ltrace uses i386 and x86_64, whereas crosstool-NG use x86 for both cases.
Fix that by detecting what bitness we're building for, and pass appropriate
i386 or x86_64 to ltrace's configure.
