 If I try to build icoutils as a universal binary, I get the following
 error:
 {{{
 ar cru libcommon.a error.o hmap.o io-utils.o intutil.o llist.o strbuf.o
 string-utils.o tmap.o ../lib/libgnu.a
 /opt/local/bin/ranlib: archive member: libcommon.a(libgnu.a) fat file for
 cputype (16777223) cpusubtype (3) is not an object file (bad magic number)
 ar: internal ranlib command failed
 }}}

 Attached is a proposed solution.
