Summary

GHC panic while building cardano-node (on github), error message displayed :

ghc: panic! (the 'impossible' happened)
(GHC version 8.10.4:
Loading temp shared object failed: /tmp/ghc54158_0/libghc_10.so: failed to map segment from shared object

Steps to reproduce

1. Have /tmp filesystem mounted with flags `noexec,nosuid,nodev' (protection against exploit execution, I believe noexec is the only culprit here)
2. Get cardano-node source code and checkout tag 1.27.0 (detailed guide here)
3. Launch compilation with $ cabal -v build cardano-node from cardano-node src directory on /home filesystem
4. Wait for the GHC panic
5. Eventually do it over again, after $ sudo mount -o remount,exec /tmp

Expected behavior
