Well, we are talking about libraries here and the host for a library is
the target of the compiler. From my reading of the manual, I maintain
my wrong advice:

-----snip from glibc-2.2.2/INSTALL-------------------------------------
`--build=BUILD-SYSTEM'
`--host=HOST-SYSTEM'
     These options are for cross-compiling.  If you specify both
     options and BUILD-SYSTEM is different from HOST-SYSTEM, `configure'
     will prepare to cross-compile glibc from BUILD-SYSTEM to be used
     on HOST-SYSTEM.  You'll probably need the `--with-headers' option
     too, and you may have to override CONFIGURE's selection of the
     compiler and/or binutils.
-----------------------------------------------------------------------

Here he cross-compiles from cygwin to m68k, BUILD to HOST, therefore
BUILD=cygwin and HOST=m86k-linux.
Using --host=$target is what Bill's script does too.

Actually, --target is not even mentionned in Glibc's manual...
Oh wait, you mean that reading the manual is a wrong advice, right? :-)

Cheers,
