Akim was talking about the 'case "$host"', I think.
The problem is that since we are testing whether a function works, we
need to _run_ that function.  When cross-compiling, this is not
possible, so checking for platforms where the function in question is
known to be broken seemed acceptable.  I suppose it would be better to
simply display a warning about how it is impossible to check for a
working fork when cross-compiling, but that doesn't make the result of
the test any better.
