Newer versions of bfd.h require definitions for the PACKAGE and
PACKAGE_VERSION macros used by autotools. Work around this by
manually defining these macros before including bfd.h.

[efi] Ensure EFI binaries comply with Authenticode requirements
Authenticode requires that the size of the raw file must equal the
size of the OptionalHeader.SizeOfHeaders plus the sum of all sections'
SizeOfRawData.

Currently, if elf2efi.c is compiled using a 32-bit HOST_CC, then the
resulting elf2efi64 binary will generate 32-bit EFI binaries instead
of 64-bit EFI binaries.
The problem is that elf2efi.c uses the MDE_CPU_* definitions to decide
whether to output a 32-bit or 64-bit PE binary. However, MDE_CPU_*
gets defined in ProcessorBind.h, depending on the compiler's target
architecture. Overriding them on the command line doesn't work in the
expected way, and you can end up in cases where both MDE_CPU_IA32 and
MDE_CPU_X64 are defined.
Fix by using a separate definition, EFI_TARGET_IA32/EFI_TARGET_X64,
which is specified only on the command line.

Currently, if you attempt to build 64-bit EFI binaries on a 32-bit
system without a suitable cross-compiling version of libbfd, the iPXE
build will die with a segmentation fault in elf2efi64.
Fix by properly handling the return value from bfd_check_format().

Access to the gpxe.org and etherboot.org domains and associated
resources has been revoked by the registrant of the domain. Work
around this problem by renaming project from gPXE to iPXE, and
updating URLs to match.
Also update README, LOG and COPYRIGHTS to remove obsolete information.

elf2efi converts a suitable ELF executable (containing relocation
information, and with appropriate virtual addresses) into an EFI
executable. It is less tightly coupled with the gPXE build process
and, in particular, does not require the use of a hand-crafted PE
image header in efiprefix.S.
elf2efi correctly handles .bss sections, which significantly reduces
the size of the gPXE EFI executable.
