Fix trace file fails on powerpc64

I see the following fails on powerpc64-linux,

(gdb) target tfile tfile-basic.tf^M

FAIL: gdb.trace/mi-traceframe-changed.exp: tfile: select trace file

These fails are caused by writing function descriptor address into trace
file instead of function address.  This patch is to teach tfile.c to
write function address on powerpc64 target.  With this patch applied,
fails in tfile.exp and mi-traceframe-changed.exp are fixed.  Is it
OK?
