Hasn't been updated since 2017 and breaks when building with a more
recent gcc (gcc5 needs to be removed as it breaks with glibc 2.30). I
tried to update this to a more recent version which didn't work either,
but as this is pretty old I'm not even sure if this package is used atm.

This update was primarily done to update rPackages.V8 to 3.0 which
doesn't depend on an ancient version of v8 anymore.

Also dropped the `-lv8_libplatform` linker flag. It seems as this now
part of `v8.so` as `v8_libplatform.so` doesn't exist anymore on recent
v8 versions in nixpkgs, but the headers are still there and there aren't
any "undefined reference to" errors while linking.

Doesn't build with gcc>=5.

Latest gcc5 release was in 2017[1], doesn't build with glibc 2.30[2].

Depends on a fairly old gcc, marked as insecure for ~2 years.

Marked as broken for >2 years, doesn't build with recent gcc.

Broken for almost 2 years, doesn't build with recent
gcc (-> incompatible with latest glibc).
