+Subject: [PATCH] build: Include configure script, be nicer about options
+
+A configure script is not included in the SpiderMonkey tarball by
+default. Also, we have to account for JHbuild passing extra unknown
+options like --disable-Werror.

+JavaScript Reference Implementation (codename SpiderMonkey). The
+package contains JavaScript runtime (compiler, interpreter,
+decompiler, garbage collector, atom manager, standard classes) and
+small "shell" program that can be used interactively and with .js
+files to run scripts.

+Wzorcowa implementacja JavaScriptu (o nazwie kodowej SpiderMonkey).
+Pakiet zawiera środowisko uruchomieniowe (kompilator, interpreter,
+dekompilator, odśmiecacz, standardowe klasy) i niewielką powłokę,
+która może być używana interaktywnie lub z plikami .js do uruchamiania
