[Bug uprobes/10273] New: uprobes fail to insert on prelinked library

["mjw at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

This might be because of the somewhat peculiar way the exelib.exp test prelinks
the library to an arbitrary address (but doesn't prelink the executable using
it), but the result is a valid executable/sharedlib.

    if {$libprelink == "yes"} {
         set prelink_bin "/usr/sbin/prelink"
         set addr "-r 0x6400000"
         set prelink_cmd [concat $prelink_bin -vfNR $addr $testso]
         send_log "Executing: $prelink_cmd\n"
         catch {eval exec $prelink_cmd} result
         verbose -log "result is $result"
    }


uprobes install fails with:
uprobe failed uprobesgcc-O3de[3865]
'process("/home/mark/src/systemtap/testsuite/libuprobeslibgcc-O3default-prelink-debug.so").function("lib_func@/home/mark/src/systemtap/testsuite/systemtap.exelib/uprobes_lib.c:11")'
