According to gzip 1.7 release note:
The GZIP environment variable is now obsolescent; gzip now warns if
it is used, and rejects attempts to use dangerous options or operands.
You can use an alias or script instead.
Fix this warning by using pipe instead

As a follow-up to r46026, this commit sets the modification
times of files inside the tarballs to deterministic values.
It uses the date of the last git or svn commit and falls
back to the old behavior if those are not available.

When creating control.tar.gz, data.tar.gz and $package.ipk
tar compresses them with default gzip options.
This includes build timestamps in their gzip headers.
By setting the GZIP env variable to -n, gzip no longer embeds
them, which is a step towards reproducibility.
