commit 409f14d9b5e47513d5c939120a33965997c8ceb2
Author: Steve Ellcey <sellcey(a)imgtec.com>
Date: Thu Feb 19 16:03:26 2015 -0800
Allow use of executable RUNPATH/RPATH when finding libraries.
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.

sync_file_range: fix standard UCLIBC_SYSCALL_ALIGN_64BIT handling
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.

posix_fadvise: handle 2 variants for SYSCALL_ALIGN_64BIT
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

ARC: Conditionalise certain relocations as provided by TLS tools only
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.
