Well...

You didn't get a "can't find" or "can't open" error message, and
libBrokenLocale.{a,so} isn't listed in the -t output. That can mean one of two
things that I can think of offhand:

(1) The LTO plugin claimed the file, which should only happen if it's a .o
file. You could try -fno-lto to rule this out.

(2) Your copy of libBrokenLocale.{a,so} is actually a script file that didn't
include any objects.

On my system, libBrokenLocale.so is a symlink to a regular shared object, and
is not claimed by the LTO plugin.

If you add -Wl,--debug=files, the stderr output will show you where the linker
actually found the file. Look for a line in the output like this:

ld: Attempt to open /usr/lib/x86_64-linux-gnu/libBrokenLocale.so succeeded

Now go look at that file: "file -L $f" (-L in case it's a symlink), "readelf -h
$f" (if it's an ELF), "cat $f" (if it's a text file).
