Use CROSS_COMPILE instead of CROSS as other projects are doing
(i.e. kernel, busybox, buildroot).
CROSS is still supported for backward compatibility only

UCLIBC_EXTRA_CFLAGS is currently added before the OPTIMIZATION flags
and OPTIMIZATION is chosen to be Os by default. But in OE we pass the optimisation
flags through UCLIBC_EXTRA_CFLAGS but they are not effective since -Os is
specified at last. So we need to change the order of these option flags

Rely on the compiler to be correctly set up to generate
appropriate code for the target variant.
This exposes the Thumb option, as it is no longer auto-selected.
The "Use BX" no longer depends on supported CPU to be selected,
so it now defaults to 'n' as it shall work by default on CPUs
that do not have BX.

Add three new blind options to set use of Thumb mode:
- COMPILE_IN_THUMB_MODE
- if set, CFLAGS will contain -mthumb
- if unset, the compiler's default is used
- HAS_THUMB
- CPUS with Thumb instruction set can select this
- use of BX depends on this
- FORCE_THUMB
- CPUs that are Thumb-only must select this
- this selects: HAS_THUMB, COMPILE_IN_THUMB_MODE and USE_BX
Also, remove leading space in Rules.mak.

All archs have now moved their generic sysdep.h header from
sysdeps/generic to sysdeps/common directory, so it is possible
to remove the sysdeps/generic directory from the include list.

A new shared object, libubacktrace.so.0 is added to uClibc
to provide backtrace functions to support application self-debugging.
This set of functions requires to dynamically load libgcc_s.so so they
need to call dlopen/dlsym that are provided by libdl. For this reason
they cannot be included into libc.so.0 but are provided by a new library.
User application that wants to use backtrace needs to be compiled with
-fexceptions option and -rdynamic to get full symbols printed and must be
linked against libubacktrace.so

Now automatically picks the correct (arch and subarch specific) impls in
favour of generic impls.
make O=/tmp/objs PREFIX=/my/sysroot -j

By default, GCC hard codes the name for ld.so to /lib/ld-uClibc.so.0
so our default should match that. If distribution makers want to change
it, they need to change the default gcc configuration as well.

Since sublevel releases are not ABI compatible we need to adjust
the soname to include the sublevel version.
This makes it possible to install ABI incompatible versions of the
library side by side so clean upgrades are possible.

Add a common header file to provide macros useful in asm code:
C_LABEL to construct the asm name for a C symbol
cfi_xxx to generate eh_frame unwind information.

This patch will re-factor and simplify sysdep headers
handling for nptl branch.
The reason is to use some useful macros in asm code (i.e. ENTRY()) that are available
only into nptl branch because are defined in sysdep.h header under the nptl folder
even if they are not related to NPTL at all (this was likely due to a bad choice done
at the early stage of NPTL porting).
This is a required steps for integrating into master branch some asm code available in
nptl branch for sh4.
The main changes are described below:
nptl/sysdeps/generic/sysdep.h (moved) ---> libc/sysdeps/linux/common/sysdep.h
nptl/sysdeps/arm/sysdep.h (moved) ---> libc/sysdeps/linux/arm/sysdep.h
nptl/sysdeps/sh/sysdep.h ---------------------|
nptl/sysdeps/unix/sh/sysdep.h ----------------|
nptl/sysdeps/unix/sysv/linux/sh/sysdep.h -----|
nptl/sysdeps/unix/sysv/linux/sh/sh4/sysdep.h -|
|(merged) ---> libc/sysdeps/linux/sh
nptl/sysdeps/unix/sysdep.h (deleted)
Similarly the mips and arm sysdep.h should be merged and updated as for sh arch.
