e6b7635c9a linux-user: Standardize on ELF_MACHINE not ELF_ARCH
PowerPC was the one outlier that defined both ELF_ARCH and
ELF_MACHINE; ELF_ARCH was defined incorrectly, necessitating
the definition of elf_check_arch.

However, the elf file header field in question is called
e_machine, so ELF_MACHINE is in fact the better name.

Mechanically change most target/target_elf.h files,
then adjust ppc/target_elf.h manually.

Do not provide a default for ELF_MACHINE.

5c3a0884ef linux-user/m68k: Expand target_elf_gregset_t
Make use of the fact that target_elf_gregset_t is a proper structure.
Drop ELF_NREG, target_elf_greg_t, and tswapreg.

bcaebf6e5b linux-user: Move elf_core_copy_regs to m68k/elfload.c
Move elf_core_copy_regs to elfload.c.
Move HAVE_ELF_CORE_DUMP, ELF_NREGS, target_elf_gregset_t to target_elf.h.
For now, duplicate the definitions of target_elf_greg_t and tswapreg.

af880af8d4 linux-user: Move get_elf_cpu_model to target/elfload.c
Rename from cpu_get_model to emphasize that this is an elf-specific
function.  Declare the function once in loader.h.

This frees up target_elf.h for other uses.

33dff5ff90 linux-user, m68k: select CPU according to ELF header values
M680x0 doesn't support the same set of instructions
as ColdFire, so we can't use "any" CPU type to execute
m68020 instructions.
We select CPU type ("m68040" or "any" for ColdFire)
according to the ELF header. If we can't, we
use by default the value used until now: "any".

542ca43498 linux-user: Move CPU type name selection to a function
Instead of a sequence of "#if ... #endif" move the
selection to a function in linux-user/*/target_elf.h

We can't add them in linux-user/*/target_cpu.h
because we will need to include "elf.h" to
use ELF flags with eflags, and including
"elf.h" in "target_cpu.h" introduces some
conflicts in elfload.c
