This patch tried to fix following build failure when linking the Brotli decompress lib.

Steps to replicate the issue:
1 - Attach a NULL lib to DxeIpl.inf in any project's .DSC, say OvmfPkgX64.dsc
  MdeModulePkg/Core/DxeIplPeim/DxeIpl.inf {
    <LibraryClasses>
      NULL|MdeModulePkg/Library/BrotliCustomDecompressLib/BrotliCustomDecompressLib.inf
  }
2 - Follow the EDKII'2 package build steps to build that project. Build.py would compliains with following errors.

Hi Abner,

What was the failure before this change?

This looks like something that would always break the build of source files were missing.
