From 332778973c3bca867dd2aa608b89a017a2e44b77 Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Wed, 27 Mar 2024 07:14:47 +0000 Subject: allow users to specify number of build threads lbmk otherwise uses nproc to set the number of build threads, in these places: * generic make commands in script/update/trees * crossgcc make command in script/update/trees the -T0 option is also used in script/update/release, when running tar. with this change, you can do: export LBMK_THREADS=x where x is the number of threads. when you then run lbmk, your chosen number of threads will override the default. this may be useful on a host that does not have a lot of memory.
