Compile for Windows with LO infrastructure (not the only external lib
where we do this).
Remove unneeded include of <err.h> in libeot.c that isn't used, but
Windows doesn't have <err.h> - it's a BSD / Linux thing.
Only compile libeot.la and not the eot2ttf binary (which uses err.h so
it doesn't compile on Windows).
