kurt 67e36b90b6 - use __data_start symbol to find the beginning of the data sections
and adjust boehm-gc to deal with any number of holes that may appear
between __data_start and _end. (requires -current binutils)
- work-around libpthread bugs that prevent sigsuspend() from working
in a signal handler by using pthread_suspend_np() + an arch/libpthread
specific offset to obtain the suspended thread's stack pointer.

thanks to sthen@ and jasper@ for access to other arches. discussed
