The patch was supposed to fix the problem...
There is one additional error in the build log:
/usr/bin/ld: final link failed: Nonrepresentable section on output
Don't know what this means.
The package built for me using the following:
gcc version 4.4.5 20100728 (prerelease) (Debian 4.4.4-8)
GNU ld (GNU Binutils) 2.20.51.20100305
and
GNU ld (GNU Binutils) 2.20.51.20100817
So, I don't think this is a binutils issue.
The message regarding `__canonicalize_funcptr_for_compare' suggests
that a DSO contains an unresolved reference to this function. You
might use -Wl,--trace-symbol=__canonicalize_funcptr_for_compare to
find out where the reference is comming from. Then, check how the
library is being linked. It may be that it is not being linked against
libgcc.
