Ard Biesheuvel f8d0b96629 BaseTools GCC5: disable warnings-as-errors for now
GCC5 runs in LTO mode, which means it may generate code from an
intermediate representation during the link stage, at which time
additional diagnostics are run that may emit warnings.

Some of these warnings seem to be spurious, e.g., the following
warning which is emitted when building OVMF for IA32 or ArmVirtQemu
for ARM (but not for X64 resp. AARCH64)

  .../MdeModulePkg/Library/UefiHiiLib/HiiLib.c:
                 In function 'HiiCreateGuidOpCode.constprop':
  .../MdeModulePkg/Library/UefiHiiLib/HiiLib.c:3228:10:
                 error: function may return address of local variable
                                            [-Werror=return-local-addr]
     return (UINT8 *)OpCodePointer;
            ^
  .../MdeModulePkg/Library/UefiHiiLib/HiiLib.c:3208:17: note: declared here
     EFI_IFR_GUID  OpCode;
                   ^
  lto1: all warnings being treated as errors
  lto-wrapper: fatal error: gcc returned 1 exit status

So before adding the contents of CC_FLAGS to the linker command line,
defuse the default '-Werror' by adding '-Wno-error' to DLINK2_FLAGS
for GCC5.

These files may be updated frequently.

The XMLSchema directory contains the EDK II Packaging XML definitions.  The
schema may change in the future.  It differs somewhat from the early versions
of the XML Schema.
