[Quantlib-dev] Build issue with QuantLib-SWIG-1.16

[Dirk E. <ed...@de...>]

Having updated QuantLib to 1.16 yesterday, I just tried to update
QuantLib-SWIG using the regular build process -- but I now get 

   /usr/bin/ld: error: lto-wrapper failed

Am I missing something simple?  Do I need add something to the build
dependencies?

Dirk, who is less well versed in Python than in R or C++
