Ronald Oussoren <[email protected]> added the comment:
A fairly simple change is to check if compiling a file with the specified set
of "-arch" flags works, and bail out with a nice error message if it doesn't.
Something like this works:
diff --git a/configure.ac b/configure.ac
index f0bc8c6258..e26cdc8607 100644
--- a/configure.ac
+++ b/configure.ac

I'm not entirely happy with the phrasing, but at least you'll get a clearer
message and one that indicate which configure argument can be used to fix it.
