ARM: Use /lib/ld-linux-armhf.so.3 for the hard-float ABI.
The hard-float ABI will now use /lib/ld-linux-armhf.so.3.
We detect the use of the hard-float ABI and select the
appropriate dynamic linker name. You must have a new or
patched compiler which also uses the new dynamic loader
name when the hard-float ABI is selected.

ia64: include errno.h in sysdep.h
This header uses __set_errno(), so make sure we include errno.h for it.
Otherwise, if INLINE_SYSCALL() is used and errno.h isn't included, we
hit warnings like so:
In file included from libc-start.c:36:0:

../sysdeps/unix/sysv/linux/dl-osinfo.h:79:7: warning: implicit declaration of function '__set_errno'

ia64: add matherr[fl] to libm.so plt whitelist
The ia64 math code has extra matherr functions (f and l variants),
so add them to the libm.so plt whitelist like the existing matherr
in the main code.

ia64: update abilist
For the most part, these are adding symbols from newer glibc releases that
should have been added to ia64 in the first place, but no one noticed.
There were also adding symbols from older versions, but that appears to be
an oversight in the old abilist files where the ia64 tuple wasn't added to
the symbol block.
A few symbols did get deleted, but that looks normal as no other arch has
them, and comparing to an old glibc-2.7 build, things have been this way
for quite a while.

These are the abilists as ia64 had them before being removed from the

in a follow up commit.

ia64: ucontext.h: drop __cplusplus
Building a lot of glibc files trigger warnings like so:
.../ucontext.h:52:25: warning: variably modified '_pad' at file scope
The ia64 header protects the use of __builtin_offsetof by a C++
compiler, but this builtin works just fine with C compilers, so
allow it to be used there too.

ia64: math: add __scalbn* aliases
All other ports have __scalbn* aliases pointing back to scalbn*, but
the ia64 code had omitted them. This didn't really matter as none
of the common code called them, but after a recent update, that's no
longer true. Add the aliases needed by some common code to fix link
errors with libm due to them missing.

Logic specific to ia64 used to live in the main tree in common files.

We need to update the file paths after the ia64 code was moved from

actually copied the ia64 version to the x86_64 code, so we can go
ahead and drop the ia64 version.

hppa: Remove relocation in OPD handling code.
A current bug in the hppa binutils code causes
relative relocations to be mixed with OPD relocations.
The OPD handling code in ld.so requires a relocation to
setup one of the data structures.
At startup ld.so tries to use the structure to handle
an OPD relocation *before* the structure is completely
setup by the relative relocation and this causes a crash.
This code is a workaround and a bandaid, the real fix
is in the static linker, but until then we must avoid
relocations in dl-fptr.c.
We copy dl-fptr.c from generic code, modify it, and
adjust the headers to fixup the structure at runtime
instead of having the relocation do this for us
automatically.
