Subject: [PATCH] BaseTools: output the intermediate library instance when error occurs

When a module "Module" depends on a library instance "Lib1" which depends on "Lib2" which depends on "Lib3" ... depends on "LibN", but "LibN" doesn't support the type (e.g.: SEC) of the "Module", the following error messages are printed by build tool:

<DSC path>(...): error 1001: Module by library instance [<LibN path>]
        consumed by [<Module path>]

But it's unclear to user how LibN is consumed by the Module.


With the patch, following errors are printed:

<DSC path>(...): error 1001: Module by library instance [<LibN path>]
        consumed by library instance [<Lib N-1 path>] which is
        consumed by module[<Module path>]

It doesn't print all the intermediate library instances between the Module and LibN but at least the path of Lib N-1 can help users to help how to fix the build errors.

I hope this patch can be a trigger point that a better solution could be developed by tool experts to print all the library instances between the Module and LibN.
