Thanks for the feedback everyone.  I settled on a slightly different
solution, that first extracts the (full) soversion from the built
library, then creates symlinks for each "sub-version".

It assumes that the major version is "1".  That could be circumvented
with a regex, but I'm not sure if it's worth the effort.

As an added bonus, this also creates "libbz2.so.1" which was missing too.

WDYT of this approach?  Can it be made simpler?
