Peculiar configure behaviour with cleanbuild

[Loïc Minier]

Hi!

>From parts/functy/build/config.log:
configure:4733: checking for glutInit in -lglut
configure:4758: g++ -o conftest

>&5
./configure: line 1588: g++: command not found

After adding g++ to build-packages, configure works for me and build
completes fine  :-)
