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.

"Use BX" is not available on all CPUs, so the option depends on
a correct CPU to be chosen . It is weird that e BX" then appears
_above_ the CPU selection, not below.
Move the "Use BX" after the CPU selection.

When NPTL is not enabled, and LOCALE support is used, compilation fails
with the following error:
-------------------------------------------------------------------------
MKDIR include/bits
GEN include/bits/sysnum.h
make[1]: *** No rule to make target `../..//include/bits/uClibc_ctype.h', needed by `../../extra/locale/gen_wc8bit.c'. Stop.
make: *** [pregen] Error 2
-------------------------------------------------------------------------
The problem is that "headers" is not listed as prerequisite of pregen.
These have been changed multiple times recently:
o Austin: order headers before pregen-headers

o Khem: pregen: Fix the parallel build problem in pregen target

o Khem: pregen-headers: Add new target which depends on headers.

o Carmelo: build: Fix infinite loop when no threading support is enabled
ff5e4de7088fe8d34812c2a1e604bf04be713606
In all of these commits headers was actually as prerequisite
In commit 9381d622e2411a35a5fd73a5a573eb269e2dd9c9 [nptl: fix buildsys] by Bernhard, headers was removed,
causing the problem reported above.

From: Alan Davis <adavis@ti.com>
On C6X, when trying to execute a program that has a textrel DSO, it
fails to load. The telltale line in the LD_DEBUG output is:
_dl_get_ready_to_run:779: file=''; needed by './a.out'
The corresponding DT_NEEDED entry has 'libc.so.0', but here the
filename is empty. This is what is happening in
_dl_elf_shared_library():
First, map all segments according to their permissions. Text gets
initially mapped read-only.
Then, parse the dynamic information. The dynamic table is in RW but
some of the tags may point to RO. For example, DT_NEEDED points to a
string in .dynstr which is in RO. These pointers get computed
according to the loadmap from the original mapping.
Then, in response to a DT_TEXTREL tag, the RO segment gets remapped,
thereby invaliding anything that points to it, in particular certain
dynamic tags such as DT_NEEDED.
The following patch re-parses the dynamic info after the remapping so
as to re-compute any invalid pointers.

Fix dladdr to correctly handle local function's address so backtrace_symbols
print only the function address for these function, instead of showing the name
of nearest one.
Indeed the dladdr walk through the hash table to find the nearest symbol, that
