Comment (by gnwiii@…):

 On the older system (iMac 27-inch mid-2010 (i5-760)) where the macports
 binary failed:

 $ port test gmp
 Warning: MacPorts running without privileges. You may be unable to
 complete certain actions (e.g. install).

 I assume no news is good news. For this system, GMP used
 "{{{/usr/bin/clang ... -mtune=corei7 -march=corei7}}}".

 $  $(port dir gmp)/work/gmp-6.1.0/config.guess

 The newer system (iMac Retina 5K, 27-inch, Late 2015, corei5):

 $ $(port dir gmp)/work/gmp-6.1.0/config.guess

 For this sysmtem, GMP used "{{{/usr/bin/clang ... -mtune=skylake
