Fix #85: Let each x86 configs set optimization level

Add `COPT` variable in `Config.x86_common` to set the optimization
level (defaulting to `-O2`).  Then each `Config.x86` file can set
`COPT` as desired if the default doesn't work.

Thus, `Config.x86_linux` sets `COPT` to `-O1`, but others can use the
default value.  See issue #68.
