All of the above points to some sort of C miscompilation.  The loading
code is obviously not effected given your results with custreloc.  Can
you identify which specific files involved in the upgrade break the
build?  I.e., I would be flabbergasted if the mere copying of
/usr/lib/libbfd.a into place on an old system would break the build.
Does your distribution separate the binutils into runtime and -dev
packages like on Debian?  If so, can you isolate which package is the
culprit?  When testing with custreloc or locbfd, you don't need the
-dev installed.  Have other header files on your system changed in the
upgrade?  I take it gcc itself has not.  My bet is on the headers.

When Debian unstable gets .8, I'll be happy to try and
reproduce/debug. 

Take care,
