You'll need to install musl-dev in your build system.
You might want to think about upgrading the golang version to 1.12 too?

[Aazhar]

I tried to install musl-dev on my build system, I'm having the same problem.
We are planning to upgrade golang version but not soon, we need to try to fix this in the meantime.

The problem is that x/tools/go/internal/gcimporter/iexport.go has a go1.11 build tag, and nothing else defines IExportData. While technically we only support the last two Go releases, it would be nice to support the 1.10 release if it's easy. From a quick test it looks like we could simply change the call to Embedded to call Anonymous instead. Embedded is the new name, Anonymous is the backward compatible name.

I came up against that this very morning, trying to build godoc.

I support any effort to keep this going a bit longer, if it is not a
major hurdle.

I will make the change that @ianlancetaylor suggested.
