Subject: Only use files from the first overlay that has them
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=2f5311c7ed2735926b6fb107a657e77ac331e4c1;p=builder.git

Only use files from the first overlay that has them

This allows special-casing pieces of code for some platforms without
fragmenting the directory structure too badly.
