Public bug reported:

Go binaries panic with "mmap errno 9" on qemu-user.

address@hidden:/# cat hello.go 
package main

import "fmt"

func main() {
    fmt.Println("hello world")
}
address@hidden:/# gccgo-7 hello.go -o hello
address@hidden:/# ./hello 
mmap errno 9
fatal error: mmap

runtime stack:
mmap errno 9
fatal error: mmap
panic during panic

runtime stack:
mmap errno 9
fatal error: mmap
stack trace unavailable
address@hidden:/#

Tested with qemu from git master with Debian unstable for armel.

Same binaries work fine on real hardware.
