title: Reduce application binary size in debug mode
body: <p>When I compile GTK4 &quot;Hello World&quot; application in rust I get binary with size 192Mb for debug mode. I use old SSD and I worry about it's resource as I compile and debug very frequently. I tried <code>-C prefer-dynamic</code> flag, but size of binary become 188Mb only.</p>
  <p>Is this way to make application binary size much smaller?</p>
  <p>PS: I work in win10 and use MSYS2.
  PPS: I don't have problem with release build's size. With <code>-C link-arg=-s</code> and <code>lto = true</code> the size is about 200kb</p>
