Marcel Moolenaar 4da47b2fec Add __elfN(dump_thread). This function is called from __elfN(coredump)
to allow dumping per-thread machine specific notes. On ia64 we use this
function to flush the dirty registers onto the backingstore before we
write out the PRSTATUS notes.

Tested on: alpha, amd64, i386, ia64 & sparc64
Not tested on: arm, powerpc
