Go will include windows-only files when compiling

[Chiiruno]

Issue description

Go will include windows-only files when compiling, and cause this error.

# github.com/bakape/hydron
/nix/store/360zh9xvnqzvzvl567b43960fhgq90dw-go-1.10.3/share/go/pkg/tool/linux_amd64/link: running g++ failed: exit status 1
/run/user/1000/go-link-113124839/000000.o: file not recognized: File format is ambiguous
/run/user/1000/go-link-113124839/000000.o: matching formats: coff-x86-64 pe-x86-64
collect2: error: ld returned 1 exit status

I have tested on another OS to ensure it wasn't the repo's problem, but instead this is Nix, or Nix's go expression that's the problem. Go will include a windows-only binary icon, and that will cause the above error.

Steps to reproduce

go get github.com/bakape/hydron
