Update Toolchain Build Script

[lolpro11]

Uses more threads, and fixes a "file not found error" with newlib

nproc isn't a thing on macOS (unless coreutils is installed, apparently), but from what I read, this should work:
getconf _NPROCESSORS_ONLN. You also want to keep the j in there.

How? The PARALLEL change looks good, but the arm-none-eabi replacement is a noop.

rm: cannot remove '/home/lolpro11/Documents/Ndless/ndless-sdk/toolchain/install/arm-none-eabi/sys-include/newlib.h': No such file or directory

If I compile for other architectures, by changing the TARGET variable, it will throw a No such file or directory error.
Same thing with rm .build_* and recompiling in place (I've had to do this many times due to user error)

That's not meant to be changed. Maybe that should be made clear in the file.

Ok, that's a bug. rm -f would avoid the warning.

I am aware of that, I was trying to build a toolchain for arm-linux-gnueabi in order to try and compile Linux applications for my calculator.
I feel like changing this would help if other users want to do similar things.

Right. That won't really work, the built libraries (libgcc, newlib) won't be compatible with linux.

I learned that the hard way.
Either way with or without my change the toolchain will still compile, I'm just adding the TARGET variable there for the sake of consistency.
