/* Create a new BFD as if by bfd_openr. Rather than opening a file,
reconstruct an ELF file by reading the segments out of remote memory
based on the ELF file header at EHDR_VMA and the ELF program headers it
points to. If not null, *LOADBASEP is filled in with the difference
between the VMAs from which the segments were read, and the VMAs the
file headers (and hence BFD's idea of each section's VMA) put them at.
The function TARGET_READ_MEMORY is called to copy LEN bytes from the
remote memory at target address VMA into the local buffer at MYADDR; it
should return zero on success or an `errno' code on failure. TEMPL must
be a BFD for an ELF target with the word size and byte order found in
the remote memory. */
