Add some more NEWS items

I've applied this patch to add some more NEWS items for changes I've put 
into glibc for 2.19.  The e500 port is briefly mentioned.  Now my 
localedef changes are done, I've added a more detailed note explaining the 
incompatibilities that result from the changes to make locale files depend 
only on endianness - while use of locale files built with localedef from 
a different glibc version isn't supported, I think incompatible changes 
are sufficiently infrequent to be worth mentioning.  (The first 
incompatibility is from consistently using 4-byte alignment for 4-byte 
integers in locale files; the second from making the hash function in 
locale archives always interpret bytes as unsigned char.)
