The binaries of EdkShellBinPkg are generated with EDK-Shell 1.04 release and build with Edk Compatibility & BaseTools Package
(r4631)

The following steps are can help to re-generate these binaries for customization:
1. Check out EdkCompatibilityPkg (r4631) to a directory EdkCompatibilityPkg in workspace (svn https://edk2.tianocore.org/svn/edk2/trunk/edk2/EdkCompatibilityPkg). 
2. Update to the newest BaseTools package.
2. Download EfiShell 1.04.zip from EDK Shell official release https://efi-shell.tianocore.org/servlets/ProjectDocumentList?folderID=52&expandFolder=52&folderID=45
3. Unzip it to the directory in EdkCompatibilityPkg , e.g. c:\EdkII\EdkCompatibilityPkg\Shell
4. Workaround an issue in EdkCompatibilityPkg\Shell\ver\Ver.inf to spit:
  [sources.ia32|x64]
    ia32\ver32.c

  to be:
  [sources.ia32]
    ia32\ver32.c

  [sources.x64]
    ia32\ver32.c

   since current build tools (r4630) does not support this syntax in EDK inf.

5. Under workspace directory, exectute:
   build -a IA32 -a X64 -a IPF -p EdkShellBinPkg\GenBin\EdkShellPkg.dsc -t WINDDK3790x1830
   The use of WINDDK instead of MYTOOLS is due to the fact that EDK shell source 1.04 is not
   VS2005 clean.

6. Copy the binaries from Build directory to this package. Typically the EFI binary
   of EdkCompatibility\Shell\$(INF_BASENAME).inf is generaged at:
   Build\EdkShellPkg\DEBUG_WINDDK3790x1830\$(ARCH)\EdkCompatibility\Shell\$(INF_BASENAME)\OUTPUT\$(BASENAME).efi
   for example:
   The x64 EFI image of EdkCompatibility\Shell\ver\ver.inf is generated at:
   Build\EdkShellPkg\DEBUG_WINDDK3790x1830\X64\EdkCompatibilityPkg\Shell\ver\Ver\OUTPUT\ver.efi

Note: Other\Maintained\Application\Shell\Shell.inf corresponds to Minimum shell binaries.
      Other\Maintained\Application\Shell\ShellFull.inf corresponds to Full Shell binaries.
