- Cleanup dl-vdso.c code.
- Pass `void *` as first arg to `load_vdso()`, using 32-bit type
is completely wrong on 64bit architectures.
- Split libc code and vDSO-related code.
Move arch-specific implementations into separate files.
The performance improvement is for example 50-60 times on ARMv7
and about 4 times on x86_64.

By some reason sparc ld.so cannot work properly with
statx() system call, so fallback to regular stat() family in ld.so.

Similar to glibc commit
https://sourceware.org/git/?p=glibc.git;a=commit;h=6bbfc5c09fc5b5e3d4a0cddbbd4e2e457767dae7
we need to handle Linux kernel change, which removed stat64 family from default syscall set.

In ARM_EABI mode, the pread64 syscall parameters are aligned on
64-bits. This syscall is used in rtld when processing FDPIC
relocations.
* ldso/include/dl-syscall.h (__syscall_pread): Fix definition.
(__dl_pread): Fix syscall invocation.
* ldso/ldso/fdpic/dl-sysdep.h (__DL_PREAD): Handle __NR_pread64.

For avr32 we still use gcc 4.4 compiler, so exlude the usage
of __builtin_unreachable here.

Otherwise gcc might not understand that oom() ended control-flow and
might emit an (untaken) reference to abort() in _dl_update_slotinfo()
on e.g. SH4 which breaks linking ld-uClibc.so.
Arguably -ffreestanding should prevent GCC from emitting this
'.global abort' but alas, it does not, which is another bug..
Also mark the function cold to further lower the incoming frequency and
branch probability.

This is for example required, used and tested with OpenJDK 7.
No regressions found, while running the testsuite with embedded-test.

Remove leftover code.

M5485 processor
1. Disable mmap2() if we're compiling for coldfire and fall back to mmap().
It seems to map a different file area on a 2.6.25 linux kernel.
2. Uses pc-relative addresing[1], computes ADDR_ALIGN, PAGE_ALIGN
and OFFSET_ALIGN relatively to _dl_pagesize[3].
On coldfire/M5485 _dl_pagesize is 0x2000.

Net outcome is that an allnoconfig with HAVE_SHARED is now about 88k instead
of formerly 130k.

system calls actually being inlined, so AVR32 needs to use
__always_inline instead of just inline. The attached patch changes this
for the system calls.

I got the library to compile with the attached patches, though dynamic
loader crashes early.
In buildroot I changed the architecture name by hand from sparc to
sparc64, otherwise the compiler produced 32-bit files with V9 (64-bit)
instructions. This configuration is not supported by QEMU, so I aimed
for pure 64-bit. I think Sparc64 option needs to be added to
buildroot.
The _Qp_ ops seem to be required by the ABI. This and setjmp patches
are just hacks to get the compilation further. The _Qp_ ops can be
found in glibc, would it be OK to use those?
V9 assembler requires declarations for global register use.
The mem* functions in sparc32 directory did not work. They are
actually used only by the hybrid 32-bit + V9 CPU configuration.

to _dl_setup_stack_chk_guard, as in glibc. SSP requires now binutils-2.16.1 and newer. Add NOT_IN_libc/IS_IN_libc. Began using -DSHARED in uClibc_main.c, there are more candidates in there. Move back dl_protect_relro to it's earlier place.
