[OpenWrt-Devel] [PATCH 4/4] package: fix "LTO" option resulted in building error

[Nylon Chen]

When a building package has -flto option leads to building error

We must use the gcc-ar wrapper instead of ar to invoke ar with the right
plugin arguments for handling the LTO objects when -flto is specified.
