Looking at cups/testi18n.c, this check is enclosed within a
«#ifndef __linux ... #endif» block, so most probably it would fail on 
Linux too.
Inspecting the SVN history, we can find r9455 (in trunk, shortly before 
the 1.5 branching) that adds the #ifndef block; unfortunately, the 
reasons why it has been done are very scarce:
$ LC_ALL=C svn log -v -c 9455 
------------------------------------------------------------------------
r9455 | mike | 2011-01-10 09:06:59 +0100 (Mon, 10 Jan 2011) | 2 lines
Changed paths:
   M /trunk/cups/testi18n.c

Don't require one of the UTF-8 tests to pass on Linux...

------------------------------------------------------------------------

One reason I can find about the failure is some different iconv 
behaviour of the GNU libc implementation vs other (Apple?) ones.

The possible two fixes I see are:
a) find out why such test fails even on Linux (with GNU libc), fix that 
and most probably it will pass on kFreeBSD and Hurd too
b) extend that #ifndef block like «#if !defined(__linux__) && 
!defined(__GLIBC__)» (which could be some temporary workaround in a 
Debian patch)
