[package] jemalloc/5.2.1: failed to build from source if docker configured with user namespaces #20858

Description

Package fails to build if conan install is running inside docker with enabled remapping.

The problem seems to be with AutoToolsBuildEnvironment in conan itself. There are wrong permissions on generated configure script, executable bit isn't set for some reason. Although if you disable remapping everything works fine.

Because this helper is deprecated, I think it's better to rewrite package recipe using different autotools helper. Looks like it will solve the problem because I was able to build libev/4.33 (which is also using autotools) in the same environment.

Package and Environment Details

Conan profile

[settings] arch=x86_64 arch_build=x86_64 build_type=Release compiler=gcc compiler.libcxx=libstdc++ compiler.version=11 os=Linux os_build=Linux [options] [build_requires] [env]

Steps to reproduce

Enable remapping

echo "$(id -un):$(id -u):65536" | sudo sed -n "w /etc/subuid"
echo "$(id -gn):$(id -g):65536" | sudo sed -n "w /etc/subgid"
echo "{ \"userns-remap\": \"$(id -un):$(id -gn)\" }" | sudo sed -n "w /etc/docker/daemon.json"
sudo systemctl restart docker

Enter into image:

docker run -it --rm gcc:11.4.0-bullseye

Try to build package inside container:

apt update
apt install python3-pip
pip install conan==1.61.0
printf "[requires]\njemalloc/5.3.0\n" >conanfile.txt
conan install --build -- .

That's weird for sure and probably is only related to jemalloc project.

All packages generated by Linux in ConanCenterIndex, they used Docker images available in https://github.com/conan-io/conan-docker-tools/. It's used a non-root user named as conan to build anything, exactly to avoid security flaws, but also permission errors.
