It certainly compiled OK for me on arm.
However, neither the ltrace I have in /usr/bin ("ltrace version 0.3.15.")
nor the one ("ltrace version ???.") seem to work.
For 0.3.15, ltrace /bin/true gives on stderr:

which appears to differ only in the value 0xbffffc44 vs 0xbffffc34.

well as the older version" is good news or bad news.
