There are two other packages affected: the native ilmbase build in
openexr (different issue - use a patch to remove "-Wno-long-double" as
this option is not available), and the native steps in Qt (similar
arch mismatch, Qt complains that it's building a 64-bit application
with a 32-bit version - use patch for makespecs)

Attached are the logs for glib/libiconv. You'll see where the mismatch
happens in glib-config.log:173 and libiconv-config.log:164. The core
tests are the same, but then ./configure in glib decides to to use the
x86_64* target where libiconv uses the i386*.
