Unfortunately, legacy .so files for ARM don't have a correct crtbegin file. Consequently, we have to grandfather the old __dso_handle behaviour. Add some ifdefs for ARM to allow it to use the old code until we can work out a transition. Change-Id: I6a28f368267d792c94e1d985d8344023bc632f6f Author: H.J.
