meson.build error: ERROR: Index 1 out of bounds of array of size 1.

When I try to compile PulseAudio on docker image of Ubuntu(rolling - 20.04) with this commands

    - sed -Ei 's/^# deb-src /deb-src /' /etc/apt/sources.list
    - export DEBIAN_FRONTEND=noninteractive DEBCONF_NONINTERACTIVE_SEEN=true
    - apt update
    - apt build-dep -y pulseaudio
    - apt install -y meson ninja-build
    - meson build
    - ninja -C build

then I get this error

C++ linker for the host machine: c++ ld.bfd 2.34

Seems that this doesn't work well for other git repositories and version_split is an array with only one element
https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/blob/master/meson.build#L7-13

Probably check if version_split.length() > 1: should be enough
