You can write an access wrapper for errno, compile it into a .so shared
object, and have GHCi load the .so.

Have a look at what the system's linker does to resolve this reference:
compile a C program, load it up into gdb, and disassemble the code.

See above. Also when we have a dynamically linked GHCi this problem
will partly go away for you
