It looks like tar tries to run gzip but the exec call returns "Invalid
argument". According to the execve manpage, that means:

  EINVAL The new process image file has the appropriate permission and
has a recognized executable binary format, but the system does not
support execution of a file with this format.

So, first find which gzip binary tar will use (ie check PATH) and then
try to figure out why that gzip binary can't be executed.
