sure the main executable always is loaded to correct place.

I assume pinterp_name is only ever set for the main executable.
Quick grep would indicate that this is indeed the case.

Subject: [PATCH] module: Use QEMU_MODULE_PATH as a search path
The current paths for modules are CONFIG_QEMU_MODDIR and paths relative
to the executable. Qemu and its modules can be installed / executed in
paths that are different from the current search paths. This change allows
a search path to be specified by environment variable.
An example usage for this is postmarketOS. This is a build environment for
Alpine Linux. It sets up an Alpine Linux chroot environment. Alpine's Qemu
packages are installed in the chroot. The Alpine Linux Qemu package is used
to test compiled Alpine Linux system images. This way there isn't a
reliance on the which ever version of Qemu the host system / distro
might provide.
postmarketOS executes Qemu on host system outside of the chroot
The Qemu module search path needs to point to the location of the
chroot relative to the host system.
e.g.
The root of the Alpine Linux chroot is:
~/.local/var/pmbootstrap/chroot_native/
The Qemu module search path needs to be:
QEMU_MODULE_PATH=~/.local/var/pmbootstrap/chroot_native/usr/lib/qemu/

From db186a3f83454268c43fc793a48bc28c41368a6c Mon Sep 17 00:00:00 2001
From: Petros Angelatos <petrosagg@gmail.com>
Date: Thu, 3 Mar 2016 23:58:53 -0800
Subject: [PATCH] linux-user: ignore signals 33 and 64 to allow golang
emulation
Signal 33 will always fail. This causes golang crash since
https://github.com/golang/go/commit/675eb72c285cd0dd44a5f280bb3fa456ddf6de16
As explained in that commit, these signals are very rarely used in a
way that causes problems, so it's ok-ish to ignore one of them.
Signal 64 will fail because QEMU uses SIGRTMAX for itself. This causes
golang to crash for versions earlier than
https://github.com/golang/go/commit/d10675089d74db0408f2432eae3bd89a8e1c2d6a
Since after that commit golang ignores that signal, we also ignore it here to
allow earlier versions to run as well.
