dprintf is already claimed by POSIX[1], and on at least one system

Compilation for arm (native or cross) results in this
warning:

fpu/softfloat-native.c: In function ‘float64_round_to_int’:
fpu/softfloat-native.c:387: error: control reaches end of non-void function

float64_round_to_int uses special assembler code for arm
and has no explicit return value.

As there is no obvious reason why arm should need special
code, all fpu related conditionals were removed.
The remaining code is standard (C99) and compiles for arm,
too.

There are places, like brcond2, where we know that the destination
of a forward branch will be within 127 bytes.

Add the R_386_PC8 relocation type to support this.  Add a flag to
tcg_out_jxx and tcg_out_brcond* to enable it.  Set the flag in the
brcond2 label_next branches; pass along the input flag otherwise.

Fix .rel.plt sections in the output to not only include .rel.plt
sections from the input but also the .rel.iplt sections and to define
the hidden symbols __rel_iplt_start and __rel_iplt_end around
.rel.iplt as otherwise we get undefined references to these when
linking statically to a multilib libc.a.  This fixes the static build
under i386.

Apply similar logic to rela.plt/.iplt and __rela_iplt/_plt_start/_end to
fix the static build under amd64.

Commit a0f291fc has enabled
-fstack-protector-all on all targets, as the configure test is bogus.
GCC only emits a warning and not an error if this option is not
supported, so the configure scripts doesn't detect the problem.

This patch changes the configure script to try the various flags
with -Werror in addition to catch the possible warnings.

Access the cp15.c13 TLS registers directly with TCG ops instead of with
a slow helper. If the the cp15 read/write was not TLS register access,
fall back to the cp15 helper.

This makes accessing __thread variables in linux-user when apps are compiled
with -mtp=cp15 possible. legal cp15 register to acces from linux-user are
already checked in cp15_user_ok.

While at it, make the cp15.c13 Thread ID registers available only on
ARMv6K and newer.

The recent transition to always have the DCR helper functions take 32 bit
values broke the PPC64 target, as target_long became 64 bits there.

This patch changes DCR helpers to target_long arguments, and cast the values
to 32 bit when needed.

Fixes PPC64 build with --enable-debug-tcg
