Hi Jan,

thanks for the report.

we had a fairly recent bug report that looked quite similar and was
exposed by Automake producing different rules for installation of
libtool libraries.  I'm not even sure we fixed this for good in Libtool,
but I also do not think that that bug is the same as what you see here:

In the log above, it seems to me that this:

| Applying fixup () to 
/home/janneke/vc/gub/target/mingw/build/libxslt-1.1.24/libxslt/.libs/libxslt.la
| Running file_sub
|   ([("libdir='/usr/lib'", 
"libdir='/home/janneke/vc/gub/target/mingw/build/libxslt-1.1.24/libxslt/.libs'")],
 
'/home/janneke/vc/gub/target/mingw/build/libxslt-1.1.24/libxslt/.libs/libxslt.la')
|   {}


hints at the actual issue: you are rewriting the install directory name
to point to below the build tree.  That is not right.  I'm assuming that
you do that in order to work around the other error you reported, namely
false linking against files below /usr/lib.

I suggest you try out the sysroot fix with upcoming Libtool 2.2.12 and
disable the gub rewriting of libdir in the .la file then, as that is
what is (rightly) confusing libtool, if I'm reading things correctly.

Thanks,
Ralf
