Sys signal: fix typo
configure: Fix --download-sowing error with 'changing file permissions' of untared files.

The following error is triggered by 'git export' adding
'pax_global_header' to tarballs.  Some veriants of 'tar utils'
see this as first entry [file] in the tarballs TOC - causing
error with 'dirname' detection.
