* This change was introduced in commit 9381d622e2411a35a5fd73a5a573eb269e2dd9c9
which rendered uclibc not booting on mips targets. Restoring it makes
it work again.

Now automatically picks the correct (arch and subarch specific) impls in
favour of generic impls.
make O=/tmp/objs PREFIX=/my/sysroot -j
works now as expected (both out-of-tree as well as parallel-safe).

The TLS merge 534661b91c9849 introduced multiple style problems as well as
random breakage:
- missing _dl_free
- incomplete parametrization of _dl_lookup_hash
- restore FDPIC handling in _dl_lookup_hash

Some powerpc machines can support 64k pages, enabled by the
CONFIG_64K_PAGES option in linux.
However, the uClibc dynamic loader won't currently work on these
machines, as it uses hard-coded values (PAGE_ALIGN, ADDR_ALIGN and
OFFS_ALIGN) in the ldso architecture-specific headers. When running on
a kernel with 64k pages, ld.so tries to mmap with 4k-aligned addresses,
rather than 64k, so mmap fails with -EINVAL.
When booting a 64k machine with a uClibc dynamic linker, init fails
with:
/init:500: can't map '/lib/libc.so.0'
/init:500: can't map '/lib/libc.so.0'
/init:500: can't map '/lib/libc.so.0'
/init: can't load library 'libc.so.0'
Kernel panic - not syncing: Attempted to kill init!
This change allows ld.so determine these alignment masks at runtime,
rather than compile-time. Since we have the _dl_pagesize variable
available, we can use that to generate the appropriate masks.
Since almost all of the architectures can use the common definitions for
the _ALIGN macros, we can consolidate them all in ldso.h, and override
in the sysdep headers where necessary (ie, mips).
This allows me to start a uClibc-based root fs on a 64k machine.

syscall.h should not have it's own version of __set_errno, instead syscall.h should
include errno.h(see powerpc) since errno handling depends on threads/no threads.
I leave the the fixing of syscall.h since there might be some smaller compile problems.

Added new asm for MIPS to be tested.
All arches should retest.

Add elf_machine_dynamic() and elf_machine_load_address() for
all archs. elf_machine_dynamic() replaces the #ifdef mess to
get at the GOT. elf_machine_load_address() is needed to execute
ldso directly, this is not complete yet.
I probably broke one or two archs(only tested PPC) so please
try and report problems. For a report to be useful you need
to enable __SUPPORT_LD_DEBUG_EARLY__ and __SUPPORT_LD_DEBUG__

Mips did not honour the LD_BIND_NOW env. variable or the DT_BIND_NOW flag
in the dynamic section.

Andrew de Quincey, who has been most helpful getting this sorted
out, thanks. Thanks also to Peter Mazinger who did alot of testing.
Removed all traces of dl_parse_copy_information() since it is no longer used.

- Replace all open coded dynamic handling with a function. Reduces size.
- Fold special MIPS dynamic code into the dynamic_info item.
- Add RELRO support.
- Support linking with "-z now".
- prepare for DT_RELACOUNT/DT_RELCOUNT optimization.
- Add -z now to ld.so linking, this is what ld.so does anyway so
let the linker know that.

only the global GOT entry relocations for the loaded shared libs were being
handled. This made applications segfault when using un-fixedup symbols. After
many hours debugging to track down the problem, this patch makes the mips port
happy again.

Hi Manuel & Erik
I think I know why MIPS is broken. _dl_perform_mips_global_got_relocations() is
broken. It will due to my latest changes reloctate ldso. This
function needs to die and its job should be done inside _dl_parse_relocation_information().
It is mostly a copy and paste job,
Also PERFORM_BOOTSTRAP_GOT and PERFORM_BOOTSTRAP_RELOCATION should be fixed, they
use symbols which aren't passed as arguments.
