Recent runs of the test suite on x86_64 machines shows a failure for the 32-bit
mmap syscall test. Looking at the linux/arch/x86_64/ia32/ia32entry.S shows a
number of different function entries for the 32-bit code beginning with
"sys32_". Many of these are wrappers for the 64-bit versions. However, some such
as sys32_mmap do not call the 64-bit implementation. Thus, that test fails.
