"BaseTools/Scripts/GccBase.lds" discards the gnu_debuglink section --
intentionally, from commit efe690cab3fb5 ("BaseTools GCC: add unified
GCC linker script for all archs and versions").
If this section is necessary for debugging, then why does the DEBUG
build work? In other words, why does the DEBUG build contain
gnu_debuglink despite the discard rule? Ard, any idea?
