[pkg-go] Bug#1069310: FTBFS: tests failed

[Reinhard Tartler]

I spent about half an hour looking at this, and wanted to share my thoughts:

- the build / tests succeed on all architectures but mips64el
- the panic in question appears to come from here:
https://sources.debian.org/src/golang-github-hanwen-go-fuse/2.4.2-2/fuse/print_linux.go/#L13
--
a map[int64]string is being set with the key "syscall.O_DIRECT" to the
value "DIRECT".
- that map is pre-initialized here:
https://sources.debian.org/src/golang-github-hanwen-go-fuse/2.4.2-2/fuse/print.go/#L64-L80
- on most architectures, such as amd64, the constant `syscall.O_DIRECT` is
set to the value 0x4000, cf.
https://cs.opensource.google/go/go/+/master:src/syscall/zerrors_linux_amd64.go;l=627;bpv=0;bpt=1
- on mipsel64, the value is set to 0x8000, cf.
https://cs.opensource.google/go/go/+/master:src/syscall/zerrors_linux_mips64.go;l=774?q=O_DIRECT&ss=go%2Fgo&start=11
- this value conflicts with
https://sources.debian.org/src/golang-github-hanwen-go-fuse/2.4.2-2/fuse/print.go/#L77
so
we now get conflicting values for the same key. This explains the message
"panic: DIRECT (8000) overlaps with LARGEFILE (8000).
