Hi Arne,

of course I did delete the ccache between my multiple builds to verify the co=
mmit. To play it safe, I hard reset using git, checked that all folders (buil=
d, ccache, etc.) are gone and restarted the build after gettoolchain and down=
loadsrc.

Sorry, I did not know that there are still a lot of machines with low ram tha=
t we are using to build ipfire. My hope was that these machines have disappea=
red over the last years.
Additionally, I do not have the ability to test all ipfire arches, as mention=
ed, the patch needs testing by others.

I also thought of adding a manual parameter for developers that somehow manua=
lly sets the parameters for parallel build, but since the MAKETUNING paramete=
r already exists and is used with other packages this would just somehow mess=
 everything up.

For my builds, I can just manually apply the patch to speed up the full build=
. My thought was that sharing the patch would make sense for others.
