[PATCH] net/mlx4: Avoid stripping the glue library

[Timothy Redaelli]

Stripping binaries at build time is usually a bad thing since it makes
impossible to generate (split) debug symbols and this can lead to a more
difficult debugging.

Automated tools to generate separate packages with debug symbols (the
standard at least in Debian and derivatives distros) break if a library
is stripped, and it's very hard to notice as well as it's not an error
per se.

After IRC discussion I completely agree that this shouldn't be stripped,
thanks for the fix.

Applied to next-net-mlx, thanks.
