This script builds NSS with gyp and ninja.
This build system is still under development. It does not yet support all
the features or platforms that NSS supports.
NSS build tool options:
-h display this help and exit
-c clean before build
-g force a rebuild of gyp (and NSPR, because why not)
-j <n> run at most <n> concurrent jobs
-v verbose build
-m32 do a 32-bit build on a 64-bit system
--test ignore map files and export everything we have
--fuzz enable fuzzing mode. this always enables test builds
--scan-build run the build with scan-build (scan-build has to be in the path)
--scan-build=/out/path sets the output path for scan-build
--opt|-o do an opt build
