fix _NSIG for it.

This patch fixes position-independent executables (PIEs) for Thumb-2. In
Thumb assembly, instructions reading pc give a value 4 greater than the
address of the instruction, rather than 8 greater as in ARM mode, so the
offset to the GOT needs to have the right offset. (The Thumb-1 code
already gets this right; it's the code shared by ARM and Thumb-2 that
needs fixing.)

in string.h and strings.h. This caught unguarded string ops in
libc/inet/ethers.c __ether_line_w() function.
I will wait for fallout reports for a week or so,
then continue converting more libc_hidden_proto's.

The attached patch adds support for compiling arm uClibc as pure Thumb code.
This is needed because some recent ARM codes do not implement traditional ARM
mode. Specifically:
* Cortex-M1 - An extremely minimal FPGA based core that only implements
Thumb-1 (aka ARMv6-M).
* Cortex-M3 - A Thumb-2 only ARMv7-M core.
Most of uClibc already builds in Thumb mode, all that is left are a handful of
assembly bits.
Tested on arm-uclinuxeabi.

a problem where the linker was trying to use the wrong symbol name for the
init function.
Define SYMBOL_PREFIX as _ in Rules.mak for h8300, bfin, i960,
microblaze, and v850. Add -D__UCLIBC_UNDERSCORES__ in CFLAGS for targets
which define SYMBOL_PREFIX as _. Remove defines and undefs from
uClibc_arch_features.h of each target.
Add $(SYMBOL_PREFIX) to __uClibc_init when passed by ld option -init.

Import INTERNAL_SYSCALL macro for i386 from glibc.
Use above macro in posix_fadvise implementation if an arch defines it.

The patch below tweaks the ARM nommu startup code so that doubleword stack
alignment is preserved. This is required on EABI targets.

Put the call_via_rx code into each executable - call_via_ip cannot
possibly work if called through the PLT! ldso requires this code
too as it is not linked with the crt stuff and thumb ldso does
make calls via a register.
The patch puts the code into crti.S so that it is linked into
every normally built application (if thumb or interworking is
selected). This is only 30 extra bytes and it works - the previous
code did not because nothing both implemented and exported the
APIs (they were in libgcc, but not in the version script).
crti.S and crtn.S is also brought up to date with GCC 3.4.4 - this
is essential for thumb support because the .init and .fini sections
must use arm or thumb code to match the compilation of the libraries.
Note that code which pushes stuff into .init or .fini must be
compiled with or without -mthumb to match the uclibc compilation -
and gcc itself (which does do this) must therefore be compiled to
match.
