Comment:
The attached patch detects failed symbol lookups. It also corrects the
bad relocation a certain type of non-exported symbol (the "approx_tab"
issue mentioned above).
The patch does not address the original question of why I had an undefined
symbol reference crash ghci. However, at least ghci will give a proper
error rather than a segfault.
The patch was validated against HEAD. There were 7 unexpected failures,
the same unexpected failures seen in a validate run in which
{{{rts/Linker.c}}} was not patched.
