They have not touched t-arm-elf. Instead they have created 
t-aprofile where they have recipes for a huge collection of 
libraries. They also have used the exclusive method and only a 
real guru can understand what this file is doing. I think there 
will be more than 10 different libraries built.

Somewhere in configure options they have put an option that tells 
configure to use this file instead of t-arm-elf.
