Hi Frédéric, I should have mentioned that I only tested on Slackware64, so 
thanks for checking the process on 32-bit Slackware.

Could you try adding -fPIC to line 82 of the SlackBuild so it looks like this:

CXXFLAGS+="$SLKCFLAGS -std=c++11 -fPIC"

The error message suggests that this is the issue.
