Run away screaming.  Really.  If it ain't broke, don't fix it.
Building linux->{windows,solaris,hpux,zos,os400} cross-compilers
is a Big Hairy Deal, and you don't want to do it.
Unless, that is, you like doing things the hard way.

I'm one of the guys who likes doing things the hard way,
and even I'm scared at tackling that.
