Comment(by blb@…):

 It looks like icu's configure script thinks that having even one -arch
 flag means universal mode is enabled.  Without any -arch, it says:
 {{{
 checking whether byte ordering is bigendian... no
 }}}
 but with MacPorts trunk adding just {{{-arch i386}}}:
 {{{
 checking whether byte ordering is bigendian... universal
 }}}
 configure has:
 {{{
     # Check for potential -arch flags.  It is not universal unless
     # there are some -arch flags.  Note that *ppc* also matches
     # ppc64.  This check is also rather less than ideal.
     case "${CC} ${CFLAGS} ${CPPFLAGS} ${LDFLAGS}" in  #(
       *-arch*ppc*|*-arch*i386*|*-arch*x86_64*)
 ac_cv_c_bigendian=universal;;
     esac
 }}}
 so it seems any -arch will set off its universal belief, and hits the
 error.  FWIW, the error appears to be related to paths that include some
 sort of type size:
 {{{
 DYLD_LIBRARY_PATH=../lib:../stubdata:../tools/ctestfw:$DYLD_LIBRARY_PATH
 ../bin/genbrk -c -i ./out/build/icudt42b -r brkitr/word_POSIX.txt -o

 [suff=/cnvalias.icu], [itempath=], [nextpath=./out/build/icudt42b],
 [checklast4=false]
 rest of path (IDD) = ./out/build/icudt42b
                                          ^
  -->  ./out/build/icudt42b/icudt42l/cnvalias.icu
 ...
 }}}
 Note the {{{icudt42b/icudt42l}}} where it appears to be trying both 42b
 and 42l; without -arch, it only uses one (icudt42l).
