This script builds NSS with gyp and ninja.

NSS build tool options:

    -h               display this help and exit
    -c               clean before build
    -cc              clean without building
    -v               verbose build
    -j <n>           run at most <n> concurrent jobs
    --gyp|-g         force a rerun of gyp
    --opt|-o         do an opt build
    --target|-t      specify target architecture (e.g., x86, x64, aarch64)
    --clang          build with clang and clang++
    --gcc            build with gcc and g++
    --msvc           build with MSVC
    --scan-build     run the build with scan-build
                     --scan-build=<dir> sets the output path for scan-build
    --disable-tests  don't build tests and corresponding cmdline utils
    --pprof          build with gperftool support
    --asan           enable address sanitizer
    --msan           enable memory sanitizer
    --ubsan          enable undefined behavior sanitizer
                     --ubsan=bool,shift,... sets specific UB sanitizers
    --fuzz           build fuzzing targets (this always enables test builds)
                     --fuzz=tls to enable TLS fuzzing mode
                     --fuzz=oss to build for OSS-Fuzz
    --sancov         do sanitize coverage builds
                     --sancov=func sets coverage to function level for example
    --emit-llvm      emit LLVM bitcode while building
                     (requires the gold linker, use clang-3.8 for SAW)
    --no-zdefs       don't set -Wl,-z,defs
    --test           ignore map files and export everything we have
    --ct-verif       build with valgrind for ct-verif
    --nspr           force a rebuild of NSPR
    --with-nspr      use the NSPR build at the given locations
                     --with-nspr=<include>:<lib> sets include and lib paths
    --system-nspr    attempt to use system nspr
                     shorthand for --with-nspr=/usr/include/nspr:
    --system-sqlite  use system sqlite
    --enable-fips    enable FIPS checks
    --enable-libpkix make libpkix part of the build
    --mozpkix-only   build only static mozpkix and mozpkix-test libraries
                     support for this build option is limited
