nss: do not force -j1
|Reported by:||Owned by:|
As noted in the ticket for 3.53,
When using the Makefiles, NSS can be built in parallel, speeding up those builds to more similar performance as the build.sh/ninja/gyp system. (Bug 290526)
Therefore, stop forcing -j1 and remeasure for parallelism=4 for the build (unfortunately, tests seem to be single-threaded).
