In reality, there is really only one type of failure being pointed out here,
the fact that 32-on-64-bit executables have short user backtraces. The failures
are magnified because the test executable gets compiled lots of different ways
- different levels of optimization, with/without prelink, etc.

From the systemtap.log file for a 64-bit executable:

====
 0x4005f0 : main_func+0x0/0x50
[...suite/uprobesgcc-O3-m64-debug-uprobeslibgcc-O3-m64-debug_exe]
 0x400658 : main+0x18/0x30
[...suite/uprobesgcc-O3-m64-debug-uprobeslibgcc-O3-m64-debug_exe]
 0x381081ecdd : __libc_start_main+0xfd/0x1d0 [/lib64/libc-2.12.so]
 0x400529 : _start+0x29/0x2c
[...suite/uprobesgcc-O3-m64-debug-uprobeslibgcc-O3-m64-debug_exe]
====

Here's the same backtrace, but for a 32-on-64-bit version of that executable:

====
 0x80484c0 : main_func+0x0/0x50
[...suite/uprobesgcc-O3-m32-debug-uprobeslibgcc-O3-m32-debug_exe]
====

The test script (in systemtap.exelib/libmarkunamestack.stp) calls      
print_ubacktrace().

On x86_64 rawhide (3.11.0-0.rc0.git7.1.fc20.x86_64), this test passes
completely.
