The problem is that gcc assumes to have the i386 (read i386 != i486 or anything newer) avaliable when it compiles a 32 bit binary. With that instruction set, it does not have atomic operations available. INstead of the inline stuff, gcc then emits a library call that ends in an unresolved symbol. If you specify any -march=whatevernewertargettocompilefor to gcc the builtin is inlined with something usable. But since the default is different we might run into trouble more often than not.
I am thinking how to solve that without braking anything. So this will come in some time, but for now 32 bit gcc linux builds do not get that.
