Given that the tools_def.template file is what contains reference to the path to the GccLto binaries it is better aligned to put these in the Basetools folder. This also helps CI and builds because the build system will fail if it can't locate these files. Example of change: https://github.com/microsoft/mu_basecore/commit/a307f99dacb6641ce6fe54e7c9ece42670fba26e tools_def.template chanages: https://github.com/microsoft/mu_basecore/commit/a95abc174e2c1a049321254d57200b6f2ec2e613 and second change to fix error: https://github.com/microsoft/mu_basecore/commit/644a7f1bafee23c5f07903f9d2aa60b6ee972e7e
