This cannot work as ${workpath} is a directory and you cannot redirect
output to a directory, you would have to specify a regular file.

Can you rely on the extracted filename that is stored in the .gz? Then
most extract options can be left on the default values:

extract.pre_args -d
extract.mkdir yes

By default, the extract command will be executed inside extract.dir,
which would be ${workpath}. The extract.mkdir option will create
${worksrcpath} first and extract to the new directory. This should
simplifies the following configure/build/destroot commands that will be
executed in ${worksrcpath} by default.
