RBM_NUM_PROCS not respected
I tried using the RBM_NUM_PROCS option (implemented in #23075 (moved)) with tor-browser-build. Unfortunately the build continued to use the default 4 cores for some reason.
If I replace the line
num_procs: '[% GET ENV.RBM_NUM_PROCS ? ENV.RBM_NUM_PROCS : "4" %]'
with
num_procs: '[% GET ENV.RBM_NUM_PROCS ? ENV.RBM_NUM_PROCS : "32" %]'
then it uses 32 cores as the default. So somehow the RBM_NUM_PROCS env var is not being detected.
