[Bug translator/10622] unsuccessful location searches for extern $variables

Guess it's related to gcc or fedora debuginfo.

On RHEL5 with self-built 2.6.32-rc6 kernel.
The latest stap works fine both with elfutils 0.141 and 0.142.

$ stap -e 'probe kernel.function("do_gettimeofday") { println($xtime) }'
semantic error: 'struct timespec' is being accessed instead of a member:
identifier '$xtime' at <input>:1:52
        source: probe kernel.function("do_gettimeofday") { println($xtime) }
                                                                   ^
Pass 2: analysis failed.  Try again with another '--vp 01' option.

Got different message, but seems stap can get location attribute.

$ stap -e 'probe kernel.function("do_gettimeofday") {
printf("xtime.tv_sec:%d\n", $xtime->tv_sec); exit() }'
xtime.tv_sec:1257921482

But failed on FC11, gcc 4.4. The error message like previous comment,
also as comment #11 of bug # 9738.
