While I'm not much of an expert on the topic, I suspect it's mostly
due to the number of custom tools that are compiled for the host
environment in order to build Haiku. There are tools that create BFS
images and populate them with Haiku binaries at build time, set their
mime types, attributes, etc. They are compiled with the host compiler
and headers, and thus must be written to be portable and support each
host environment. My guess is that several of these are not yet
endian-safe :(
I have heard at least one or two people in the past trying to get
Haiku compiled from a PPC host, with various issues cropping up. I
don't think they were ever resolved though.
