[Buildroot] Why does boost require bzip2

[Will Wagner <will_wagner@carallon.com>]

Hello,

Does anyone know why the boost package requires bzip2? I am wanting to 
build a very small rootfs and require only a single boost library, I 
want to avoid the overhead of having the bzip2 library in my target fs.

If I change the boost package it still manages to build all the 
libraries so I can't work out which libraries need bzip2. (I also have a 
build failure when trying to build the boost context library, it is 
failing because my arm target doesn't support the assembler, I'll look 
into that error separately).

Thanks
Will
