Note that this is only guaranteed to work on your machine, and only as
long as you don't upgrade libxml2.
You can't rely on a fixed number of -L options : there may be no -L
options at all.
On Cygwin, xml2-config --libs outputs

-L/usr/lib -lxml2 -lz -liconv -lm

but -L/usr/lib is redundant and the next version may decide to omit it
altogether.

No, sorry; I'm not familiar with automake.
You may want to file a bug against automake because this error message
is incorrect; apparently it didn't recognize the `` construct.
