When a target does not support a vdso, we generate a sigtramp page.
The only thing on this page is a (set of) signal return syscalls.
We do not need to narrowly restrict the vdso_sigreturn_region;
simply record the entire page for all such targets.

These variables will be populated from the vdso, and used
for detecting whether we are executing the sigreturn.

Rename to elf_check_machine to match ELF_MACHINE.

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.

We already provide ELF_DATA based on TARGET_BIG_ENDIAN.

Use TARGET_PAGE_SIZE instead. If the target page size may vary,
using a different fixed size is wrong.

Rename from vdso_image_info to avoid a symbol clash.
Define HAVE_VDSO_IMAGE_INFO to signal the external definition exists.
Provide fallback versions for other targets.

Turn the fallback macro into a function. This will produce
a link error if the other macros are set up incorrectly.
