TestCharsets fails with Golang 1.6

[onlyjob]

=== RUN   TestCharsets
--- FAIL: TestCharsets (0.00s)
        iconv_test.go:38: test 0
panic: runtime error: cgo argument has Go pointer to Go pointer [recovered]
        panic: runtime error: cgo argument has Go pointer to Go pointer

Apparently Go pointer to Go pointer is no longer allowed: golang/go#12416

Or maybe this problem is due to absence of test data in /usr/local/lib/go-charset/datafiles...
Anyway error message is rather confusing... Please investigate.

When I try to run tsc.go, I get this error:
charset: cannot open "charsets.json": open /usr/local/lib/go-charset/datafiles/charsets.json: no such file or directory

I'm sure you have long since moved on, but I finally identified and fixed the cgo issue. Closing this.
