Dear all,
I found some good explanation in `man make`, but some questions are
open, maybe someone can give a little bit more insight.

it takes the variable ${ALLFILES}, the :N operator removes everything
that matches, so in this case every string that begins with prebuilt is
removed.
But what does the last `:` at the end of this string?
EXTRACT_ONLY+= ${DISTFILES:N*.mod\:*:N*.mod:C/:.*//}
So if I understood this correctly at takes the variable ${DISTFILES} and
removes everything that matches `*.mod:*`.
Then as next it removes everything that matches `*.mod`.
As last step a regular expression is executed that removes `:*` (the *
is here any character), so the string `ksdjhe:sdhg34` is changed to
`ksdjhe`.
Thanks
Matthias
