---------------------------------+------------------------------------------
 When compiling mips-elf-gcc it complains that libiconv, libiconv_open, and
 libiconv_close are missing as symbols. To avoid this compilation error
 LIBICONV_PLUG should be defined when including /opt/local/include/iconv.h
 (My quick and dirty fix was to define it in the h-file during the
 compilation).

 The second problem is that several make scripts use -arch X86_64 as
 compilation flag, which results in errors. Removing this argument makes
 the port compile and install.
