Bail out if there seem to be no text symbols.

Found by Ævar in an IBM pSeries POWER7 Fedora Linux box.
All the text symbols (code) seemed to be 'D' (data).

There might be something further to fix regarding the use of 'nm'
(or maybe 'ar'?) in this particular box, but this change makes
the test more robust against surprising nm results.
