Ok - that explains it:

configure:68713: checking for dlopen in -ldl
configure:68738: 
/home/schoelle/Code/Pike-v8.0.388/build/openbsd-6.0-amd64/smartlink gcc 
-o conftest -g  -fvisibility=hidden -O3 -pipe -ggdb -funswitch-loops 
-I/usr/local/include -I/usr/X11R6/include 
-I/home/schoelle/Code/Pike-v8.0.388/src 
-I/home/schoelle/Code/Pike-v8.0.388/build/openbsd-6.0-amd64 
-L/usr/local/lib -R/usr/local/lib -L/usr/X11R6/lib -R/usr/X11R6/lib 
-L/usr/lib/gcc-lib/amd64-unknown-openbsd6.0/4.2.1 conftest.c -ldl  -lm  >&5
/usr/bin/ld: cannot find -ldl
collect2: ld returned 1 exit status

Looks like -ldl is not needed on OpenBSD. The functions are available as 
documented here:

http://man.openbsd.org/OpenBSD-current/man3/dlfcn.3

I have removed the inclusion of -ldl into LIBS in the configure script.

Now, things are very messy with lots of errors. Will continue to dig 
further.

Current output is here:
