Missing "-ldl" in bootstrap/Makefile

[mingodad]

When trying to build this project on Ubuntu 18.04 I'm getting this error:

bootstrap-c2c.sh
setting C2 environment
make: Entering directory 'c2compiler/bootstrap'

But after adding -ldl to bootstrap/Makefile the it build fine:

Weird that it builds without that flag on my system...fixed. Thx!
