Comment (by mfeiri@…):

 Didn't this cause hard build/update errors for anyone who ever installed
 gcc in macports before r125552? Anyway, while #42500 is still not entirely
 resolved, the destroot location of libunwind-headers was changed in
 r127042. Removed the explicit build conflict in r127045.
