Comment:
There is a new patch for review in branch `bug_28672_v7`:
https://gitweb.torproject.org/user/boklm/tor-browser-
build.git/commit/?h=bug_28672_v7&id=082b4fd8759ef9e88317940d77d091291d0363df
This gomobile patch is fixing the issue with `/tmp/gomobile-work-
XXXXXXXXX` paths:
https://gitweb.torproject.org/user/boklm/tor-browser-
build.git/tree/projects/gomobile/0001-If-the-GOMOBILE_TMPDIR-env-variable-
is-defined-
use-t.patch?h=bug_28672_v7&id=082b4fd8759ef9e88317940d77d091291d0363df
However there was still an issue with a `/tmp/go-buildXXXXXXXXX`. I tried
fixing it with a `sed -i -E -e 's#(/tmp/go-build|/tmp/go-
link-)[0-9]{9}/#\1XXXXXXXXX/#g' libgojni.so`, but this did not fix the
issue completely as there was still differences after that:

So I added added a patch to go, to make it use a fixed tmp directory, if
the directory does not exist yet, which is fixing the issue:
