[PATCH v1 2/4] BaseTools/build: Set MakefileName

["PierreGondois" <pierre.gondois@arm.com>]

From: Pierre Gondois <Pierre.Gondois@arm.com>

Running the following command:
  python3 build/build.py -a AARCH64 -t GCC5
  -p ArmPlatformPkg/ArmPlatformPkg.dsc -b DEBUG libraries
triggers the following error:
  make: *** Build/ArmPlatform/DEBUG_GCC5/AARCH64/MdePkg/Library/
  BasePcdLibNull/BasePcdLibNull: Is a directory.  Stop.

Indeed, MakefileName is set to en empty string. Setting MakefileName
resolves the error.
