Comment (by jpmasseria):

 Here's what's in my `config.log` related to `-ldl`:

 {{{
 configure:10619: /home/johnma/mygcc -o conftest -g -O2 -fno-stack-
 protector   conftest.c -ldl   >&5
 /tmp/ccqfJgej.o: In function `main':
 /home/johnma/ghc/conftest.c:99: warning: Using 'dlopen' in statically
 linked applications requires at runtime the shared libraries from the
 glibc version used for linking
 /home/johnma/rpi-toolchain/rootfs/usr/lib/arm-linux-
 gnueabihf/libdl.a(dlopen.o): In function `dlopen':
 (.text+0xc): undefined reference to `__dlopen'
 collect2: error: ld returned 1 exit status
 configure:10619: $? = 1
 }}}

 This is strange because I am using the tool chain recommended here:
