When trying to build for 32-bit ARM (linux/arm), you get: ``` pkg/remote/client.go:120:35: cannot use 0xffffffff (untyped int constant 4294967295) as int value in argument to fmt.Errorf (overflows) ``` Pass the constant as unsigned 64-bit integer, which is what the underlying snappy code is doing (it's casting the argument to an uint64 and comparing against 0xffffffff, which in Go means it's comparing against uint64(0xffffffff)). Since this is just an error message, it shouldn't matter, but let's be consistent. Signed-off-by: Marcelo E. Magallon <marcelo.magallon@grafana.com>
mem requested review from mstoykov and codebien and removed request for a team 
| Sorry about recreating the PR instead of reopening the old one (#132). My bad. I reworded the commit message to reflect the fact that this is not specific to ARM. The reason why I would like to have this is because I would like to run k6 on linux/arm (Raspberry Pi and whatnot). |

Hey @mem,
I think my comment on the previous PR #132 (comment) is still valid, can you take a look into it, please?

| "size: %d, limit: %d", len(b), math.MaxUint32) |
I think something like that could be better as self-documenting code so we don't have to remember why we did it. @mem Can you try if it works on your 32-bit arch, please?
