Re: [Patch 1/1 V2] BaseTools: Create ".cache" folder when initialize Build object

["Michael D Kinney" <michael.d.kinney@intel.com>]

Bob,

Thanks for the quick fix.  I have tested this change with
the Vlv2TbltDevicePkg updates that are under review that
include the use of a PREBUILD script.  It works when the
.cache dir is not present.
