Align sp to 8-byte boundary as required by EABI.

This is especially important for non-leaf functions; GCC optimizes codes
based on assumption that sp is aligned properly.

Mostly fix broken earmv5 userland compiled by GCC10 due to alignment
faults in ld.elf_so, where {ld,st}rd are used for [sp, #8x].

No regression for ATF is observed for earmv[67]{,hf}{,eb}.

Align sp to 8-byte boundary as required by EABI.
IIUC, this change only affects libc compiled for ``Thumb-mode userland'',
which we've not officially supported yet.

Fix previous. For Thumb-1:
- sp cannot be manipulated directly
- {add,sub}s should be used instead of {add,sub}

Trailing whitespace

The _INVOKE_CERROR macro deals with thumb so simplify the code (at the
expense of a couple more instructions).

Do previous differently by pushing even number of registers and remove
strange r7 usage.

Do previous differtly by pushing two registers in the same way as the
_INVOKE_CERROR macro

Fix a comment

Rebase to HEAD as of a few days ago.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

Use PLT_SYM.

Fix the .cfi correctly.

Fix build by matching .cfi/#if.

only emit cfi if __ARM_EABI__ && __UNWIND_TABLES__

Use less got, add END(), make thumb tolerant.

More thumb support

Use RET and RETc macros for returning.

NetBSD/acorn26 has been using APCS-32 for years, so unifdef -U__APCS_26__.

Merge the nathanw_sa branch.

* Make this work with ELF.
* We don't appear to have an internal name for setcontext(), so
  don't use one (i.e. call setcontext(), rather than _setcontext()).

XXX Namespace considerations wrt. the ucontext functions are not
consistent -- need to revisit.
