Subject: [edk2-devel] [PATCH] BaseTools: Normalize case of pathname when evaluating Macros.

From: Mingyue Liang <mingyuex.liang@intel.com>

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2880

Currently, When doing the Incremental build, the directory macros extended to absolute path in output Makefile, which is inconsistent with the output of Clean build.

When we do macro replacement, we can't replace macro due to inconsistent path case, which results in inconsistent display of incremental build and clean build in makefile.Therefore, the path is converted to achieve the correct macro replacement.
