I haven't verified this, so this is just a guess, but perhaps without -trimpath the go tool is using the prebuilt runtime/cgo.a, which was built on a system with a C compiler. When you add -trimpath, the runtime/cgo package needs to be rebuilt in order to trim the paths. Unfortunately, that rebuild fails, as the system you are building on does not have a C compiler.
