[opensuse-packaging] New macro to limit resources allocation per thread

Hello all, For use in libreoffice, chromium and others I've created macro that should allow you to limit jobs based on some constraints you can set later on in the spec to avoid OOM crashes. The usage is pretty straight forward (Once it is accepted in Tumbleweed): === BuildRequires: memory-constraints %build # require 2GB mem per thread %limit_build -m 2000 make %{?_smp_mflags} ==== Here the _smp_mflags vaule for 8GB machine would be 4 while default is number of cores (lets say 16)... Both macros %jobs and %_smp_mflags are overriden as such the integration should be really painless if you need to do something like this. Tom
