Dear Maintainer,

The TestPrintAssemblyErrorMessage test fails on armhf because it
hardcodes 64-bit base addresses.

I am forwarding a patch from Ubuntu that skips this test on armhf
architectures.

Ubuntu bug reference:
https://bugs.launchpad.net/ubuntu/+source/golang-github-google-pprof/+bug/2146957

The patch is attached.
