Reading an Obj file format using osg OBJPlugin file fails under linux distro with european local.

[mselim]

osg 3.6.5
ubuntu 19.10
xubuntu 18.04
gcc 9.2.1
intel hd 620, with mesa 19.3.4

Obj files are not read correctly using osgDB::readNode resulting into osg::Geode with vertices and normals set to 0,0,0,0. While the same code works fine on windows.

I've just re-checked with this fix (using 3.6.5 or directly pulling from master), unfortunately it's not working, but I've managed to know why it's not reading correctly the obj file, it's because environment variable LC_ALL wasn't set by default, it was (this includes almost all ubuntu distros) to nothing (empty). To overcome this issue you have to export on linux your environment variable LC_ALL = POSIX or en_US.UTF-8. I think because I do use a linux distro ubuntu with local set to a European country which floating point decimal mark (",") is different from English US ("."). That's why the parsing of obj not able to read the vertices floating points values correctly because they're written in us comma separated style i.e. x,y,z = 3.34, 6.5656, 0.9875867
