Libreoffice does not builds with parallell make

[Sergio de Almeida Lenzi]

It stops with....


   3991 [build ECH] CustomTarget/instsetoo_native/setup/versionrc^M
   3992 fatal: Not a git repository (or any of the parent
directories): .git^M


If I set PARALELL=1
it builds... but takes hours and hours....
