Sync with GNU libc, see here why r7 is not usable for
thumb mode:
https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/unix/sysv/linux/arm/sysdep.h;h=37eac192b1e2e7f53f112b16450b9ce57054e27f;hb=HEAD
Remove old OABI support.
Fixes build breakage for ARM noMMU builds.
Still no runtime testing.

For sh4/xtensa architectures there is an optimization
bug, which does not allow to compile ld.so with gcc 4.9.2.
Disable this optimization for sh4/xtensa and ld.so compile.

This option will modify ldso so that it will use the executables
RUNPATH/RPATH to find to find libraries even though this behavour
is not standard. Setting this option causes the uclibc dynamic linker
behavour to match the glibc dynamic linker.

Currently UCLIBC_SYSCALL_ALIGN_64BIT is not explicitly handled. Fix that
and make sure the special handling is done for powerpc/xtensa which use
UCLIBC_SYSCALL_ALIGN_64BIT but don't use hole punched syscall handler in
kernel.

arm/powerpc/xtensa pass @advice as 2nd arg to syscall (vs. canonical 4th)
Current code however does this for UCLIBC_SYSCALL_ALIGN_64BIT which
powerpc/xtensa also happen to define.
This is not true for ARCv2 ISA and possibly other arch of future with
64-bit even register requirement, which uses the standard syscall
handler in kernel.
Fix that by providing 2 variants of SYSCALL_ALIGN_64BIT

uClibc mainline supports NPTL which in turns depends on TLS support in
the tools (gcc/binutils), which is yet to be merged in dev branches.
However there is some non NPTL code in uClibc, added as part of NPTL
effort, which relies on certain relocations only provided by NPTL
binutils. As a result building the current upstream even for LT.old
breaks.
So conditionalize that code on tools, bu tin lack of specific versions,
we use NPTL enabling as a sign the tools are equipped to handle those
relos.

Add a configuration choice for the NaN format on MIPS (either the
standard (legacy) format or the newer IEEE 2008 format.
Change how CPU_LDFLAGS are set for MIPS. Use the same value as
CPU_CFLAGS since CC is used to do linking. This ensures consistency
between compiles and links and adds support for N32 ABI to linking.
