[lumpfish]

The systemtest build fails on Alpine Linux with

This is now resolved with the updates to docker images for the 2 test machines (by running apk add musl-dev to ensure presence of stdio.h, see adoptium/infrastructure#2026).

We now can compile system test material and get to the stage of running tests, which fail with another missing piece related to machine setup, see https://ci.adoptopenjdk.net/view/Test_system/job/Test_openjdk16_hs_extended.system_x86-64_alpine-linux/7/tapResults/ to find that there is a diagnostics package required.
