FreeBSD 10.1: build fails

[jbergstroem]

Couldn't find any other open bugs about clang compatibility, but this error probably just affects FreeBSD:

V8 seems to call g++ instead of c++ (rather clang++) which makes the build fail. If I set CC/CPP/CXX environment flags it at least builds, but fails here:

  clang++ '-DV8_TARGET_ARCH_X64' '-DENABLE_DISASSEMBLER' '-DICU_UTIL_DATA_IMPL=ICU_UTIL_DATA_STATIC' '-DENABLE_HANDLE_ZAPPING' -I../deps/v8  -pthread -Wall -Wextra -Wno-unused-parameter -m64 -fno-strict-aliasing -I/usr/local/include -O3 -ffunction-sections -fdata-sections -fno-omit-frame-pointer -fdata-sections -ffunction-sections -O3 -fno-rtti -fno-exceptions -std=gnu++0x -MMD -MF /usr/home/jbergstroem/io.js-1.x/out/Release/.deps//usr/home/jbergstroem/io.js-1.x/out/Release/obj.target/v8_base/deps/v8/src/arguments.o.d.raw  -c -o /usr/home/jbergstroem/io.js-1.x/out/Release/obj.target/v8_base/deps/v8/src/arguments.o ../deps/v8/src/arguments.cc

This is FreeBSD builder 10.1-RELEASE amd64, clang 3.4.1.

I have 2 FreeBSD boxes from Voxer to hook up to CI but it's going to have to wait post 1.0.0 for now, having the tests pass prior to 1.0.0 would be really nice though, if possible.

See https://github.com/iojs/io.js/pull/332/files for a fix. Still has lots of test failures :)

Should be better now.
