LDSCRIPT = l476rg.ld
Remove duplicate linker script definitions ## Summary A lot of linker scripts were listed twice, once for unix, once for windows. This PR cleans up the logic so they're only listed once. ## Impact Any opportunity to use a single source of truth and reduce lines of code is a win! ## Testing CI will test all build

Revert "Make: use gcc as LD" This reverts commit 45672c269db13f59bdaa417e564837e8bbb6c8c1. Because: * It's very confusing to have cc as LD. * I don't see what "-nostartfiles -nodefaultlibs" in LDFLAGS are supposed to do when we use LD directly. It would be simpler to remove them from our LDFLAGS.
