Actually, I've since managed to build u-boot with the xdev
toolchain.  There were two issues:

1) "gcc --print-file-name=include" 

About a week ago, I committed a fix to FreeBSD-CURRENT
so it now supports this.

2) Missing div/mod functions in ARM libgcc.

You can work around this by adding -lc to a couple
of places in the u-boot makefiles.  I'm also looking into
a fix for FreeBSD libgcc.  (Looks like these functions
were disabled deliberately?  I'm still digging.)
