[edk2-devel] [PATCH] Revert "BaseTools/Conf: Fix Dynamic-Library-File template"

[Konstantin Aladyshev]

Hi, Jake!

No, unfortunately I don't have any way to fix this, besides the patch revert.

To reproduce the issue you can add the mentioned PCI_* defines to some
simple DXE_DRIVER.

For example:

SimpleDriver/SimpleDriver.inf
```
[Defines]
  INF_VERSION                    = 1.25
  BASE_NAME                      = SimpleDriver
  FILE_GUID                      = 384aeb18-105d-4af1-bf17-5e349e8f4d4c
  MODULE_TYPE                    = UEFI_DRIVER
  VERSION_STRING                 = 1.0
  ENTRY_POINT                    = SimpleDriverEntryPoint
  UNLOAD_IMAGE                   = SimpleDriverUnload
  PCI_VENDOR_ID                  = 0x1234
  PCI_DEVICE_ID                  = 0x5678
  PCI_CLASS_CODE                 = 0x0001
  PCI_REVISION                   = 0x0002

[Sources]
  SimpleDriver.c

[Packages]
  MdePkg/MdePkg.dec

[LibraryClasses]
  UefiDriverEntryPoint
  UefiLib
```

SimpleDriver/SimpleDriver.c
```
#include <Library/UefiBootServicesTableLib.h>
#include <Library/UefiLib.h>


EFI_STATUS
EFIAPI
SimpleDriverUnload (
  EFI_HANDLE ImageHandle
  )
{
  return EFI_SUCCESS;
}

EFI_STATUS
EFIAPI
SimpleDriverEntryPoint (
  IN EFI_HANDLE        ImageHandle,
  IN EFI_SYSTEM_TABLE  *SystemTable
  )
{
  return EFI_SUCCESS;
}
```
It is enough to reproduce the issue.
Normally the build system should compile the driver code fine and then
call the EfiRom utility to produce the OptionROM image. But with the
d372ab585a2cdc5348af5f701c56c631235fe698 in place the driver build
fails.
