Mac OS (Mojave / Xcode 10.3) build issue..

[Erik Joelsson]

The failing build step is using nm to extract symbols from object files. 
The standard nm on Macosx/Xcode (which is llvm based) behaves 
differently compared to Linux/GNU which is from binutils. If your 
environment contains a different nm then the hotspot build will not know 
how to call it properly.

You could try to work around it by configuring with NM=/usr/bin/nm set.
