Comment (by kencu):

 This error:
 {{{
 ld: absolute addressing (perhaps -mdynamic-no-pic) used in
 icu_67::FixedDecimal::getFractionalDigits(double, int) from plurrule.o not
 allowed in slidable image. Use '-read_only_relocs suppress' to enable text
 relocs
 }}}

 Is quite commonly found when building some code archs. The fix is usually
 to do what the error is telling you to do, ie add:
 {{{
 -read_only_relocs suppress
 }}}
 to the linker args.

 You will find a number of cases in the ports tree where I did this, and
 perhaps others have done it too, I didn't look at them all. You usually
 need to restrict that linker flag to just the build archs where the error
 is generated, as it is not accepted by some other build archs.

 If you grep the ports repo for {{{read_only_relocs}}} you will find some
 reasonable-looking examples.

 As to WHY this is needed, the best explanation I have come across is here:
