Explain problems with sed.

Basically: 10.9's sed is broken, bootstrap works around this via nbsed
on 10.9, and therefore while a 10.6 boostrap's binaries will *run* on
10.9, one can't reliably build new packages.

(Thanks to jperkin@ for pointing this out.)

 Older versions of Mac OS X (with XCode, of course) provided gcc, and
 pkgsrc defaulted to using gcc.  With 10.9, gcc is no longer present
 and one must bootstrap with "--compiler=clang".  (Arguably, pkgsrc
 should default to clang on 10.9.)

 Given the 10.9 license situation, a bulk build on 10.9 (and therefore
 clang) seems reasonable, with either --abi=32 or --abi=64.  Such
 builds are almost certainly only usable on 10.9, but that is or will
