[Nix-dev] For go-wizards: Building the geth using buildGoPackage

[Sergey Mironov]

I recently tried to upgrade the go compiler up to 1.8 by
cherry-picking all related commits. The error now looks like the
following:

# github.com/ethereum/go-ethereum/vendor/github.com/karalabe/hid
cgo-dwarf-inference:2:8: error: enumerator value for '__cgo_enum__0'
is not an integer constant
cgo-dwarf-inference:10:8: error: enumerator value for '__cgo_enum__7'
is not an integer constant
cgo-dwarf-inference:18:2: error: initializer element is not constant
cgo-dwarf-inference:18:2: note: (near initialization for '__cgodebug_data[0]')
cgo-dwarf-inference:25:2: error: initializer element is not constant
cgo-dwarf-inference:25:2: note: (near initialization for '__cgodebug_data[7]')

Upstream maintainer pointed out to
https://github.com/golang/go/issues/14669 problem. I've tried adding

preBuild=''
  export CGO_CFLAGS='-O0'
'';

without success..

Regards, Sergey
