Found an interesting reference from 2003, which places the blame on  
libtool:

msg00010.html

Seems that it used to fail the -fPIC test on any warning, which I  
guess -fstack-protector will issue on an Alpha, which is fair enough.  
It seems to have been dealt with at some point in the last few years,  
and updating the package's libtool setup seems to fix this:

You should update your `aclocal.m4' by running aclocal.
[root genuine-article libmad-0.15.1b]# aclocal

This could be worked into the spec for a failing package, and even  
resolved upstream if they update their libtool setup, without needing  
to mess with architecture specific macros.
