about building the crosstools

[Chuck Robey]

I got instructions from Warner about how to build my crosstools (the FreeBSD
ones) and after a minor startup contretemps, things began to work better.  My
problem is that on doing the linking step, I'm getting a complaint that it can't
figure out how to build the  /usr/cross/usr/lib/libc.a (/usr/cross being my
toolls destdir).  I don't know how to fix this in the build, so I'd appreciate
any hints.  I mean, it *seems* to me that these tools are meant to run on my
current host (i386), not the target (arm) so it really should already know about
my /usr/lib/libc.a (or shared version)) right?
