Philippe Mathieu-Daudé 159fb790e4 hw/elf_ops: Rename elf_ops.h -> elf_ops.h.inc
Since commit 139c1837db ("meson: rename included C source files
to .c.inc"), QEMU standard procedure for included C files is to
use *.c.inc.

Besides, since commit 6a0057aa22 ("docs/devel: make a statement
about includes") this is documented in the Coding Style:

  If you do use template header files they should be named with
  the ``.c.inc`` or ``.h.inc`` suffix to make it clear they are
  being included for expansion.

Therefore rename "hw/elf_ops.h" as "hw/elf_ops.h.inc".

Peter Maydell a6819c1bd0 linux-user/flatload.c: Remove unused bFLT shared-library and ZFLAT code
Ever since the bFLT format support was added in 2006, there has been
a chunk of code in the file guarded by CONFIG_BINFMT_SHARED_FLAT
which is supposedly for shared library support.  This is not enabled
and it's not possible to enable it, because if you do you'll run into
the "#error needs checking" in the calc_reloc() function.

Similarly, CONFIG_BINFMT_ZFLAT exists but can't be enabled because of
an "#error code needs checking" in load_flat_file().

This code is obviously unfinished and has never been used; nobody in
the intervening 18 years has complained about this or fixed it, so
just delete the dead code.  If anybody ever wants the feature they
can always pull it out of git, or (perhaps better) write it from
scratch based on the current Linux bFLT loader rather than the one of
18 years ago.
