What iconv are you using? Not all iconv implementations are equal and 
the one that is in klibc is slightly different then GNU libiconv. Some 
configure scripts test for this and have different code for different 
implementations.
When building for my personal use I often just do configure 
--disable-iconv, if that isn't an option you could bypass the convert to 
UTF16 function as it doesn't make much sense on OS/2 or install GNU 
libiconv, there is a version here, 
http://bauxite.sakura.ne.jp/software/os2/#libiconv that I've never tested.
