I've checked in a change to configure.ac/configure that automatically enables
prologue searching if:
- we're running on an x86
- gcc version is less than 4

This change reduces the cases of system calls returning "<unknown>".  However,
the syscall tests still don't pass.  It appears that on the two rhel4 systems I
tried this on probes get skipped which changes the output the tests look for.

I'm unsure as to why this is happening.
