Witold Filipczyk 1f57e72212 [mozjs24] Allow build elinks with g++
SpiderMonkey was updated to mozjs24. If you want to build elinks
with ecmascript support, you must compile using g++ with -fpermissive .
There is a lot of warnings.
There are some memleaks in ecmascript code, especially related to JSAutoCompartment.
I don't know yet, where and how to free it.

Debian does not support mozjs24, so I'm going to gradually update SpiderMonkey version.
