Build with more than -j8

[buserror]

I have LOADS of cores on this server I'm building, and I see it crawling with just -j8. Here's a small patch that (in linux) increases that to the number f available threads... diff --git a/build-toolchain.bash b/build-toolchain.bash

+    BUILD_JOBS=$(grep processor /proc/cpuinfo |wc -l)

Is there some advantage to doing this in such a complicated way? Isn't BUILD_JOBS=$(nproc) sufficient?
