mcount_internal on ARM

Hi, 

I'm currently trying to build a toolchain for gcc-3.3.2/glibc-2.3.2 on
ARM. This is what I get when building glibc:

Looking at sysdeps/arm/machine-gmon.h and grepping through the sources I
don't find where mcount_internal() is implemented, but as I don't find
it for other architectures as well I assume I missed some glibc magic...
