[PATCH] build: shorten macro references

[Jan Beulich <jbeulich@xxxxxxxx>]

Presumably by copy-and-paste we've accumulated a number of instances of
$(@D)/$(@F), which really is nothing else than $@. The split form only
needs using when we want to e.g. insert a leading . at the beginning of
the file name portion of the full name.
