Some users may have libtool libs (.la) installed in their linker search paths. In this case, using -static-libtool-libs would try to link in .a's instead of shared libs. That would be harmless unless the .a was built in a way that would break linking, like non-fpic.
What we really want is "-static" here. Despite its name, it's actually less aggressive than -static-libtool-libs. It causes only internal libs to be linked statically (libbitcoinconsensus is the one were'a after).
