Comment (by larryv@…):

 The configure script decides to tack “-arch i386” onto CC for me:
 {{{
 % sudo port install nspr -universal
 }}}
 {{{
 :info:configure checking how to run the C preprocessor... ccache
 /usr/bin/clang -E
 [...]
 :info:configure checking whether ccache /usr/bin/clang -arch i386 needs
 -traditional... no
 [...]
 :info:build ccache /usr/bin/clang -arch i386 [...] -arch x86_64 [...]
 }}}
