Strange link error with -lusb on sid

[Alec Leamas <leamas.alec@gmail.com>]

Dear list,


I get the following linker error building upstream lirc on sid, updated 
as of today:

/usr/bin/ld: cannot find /lib/
/usr/bin/ld: cannot find s/libusb-0.1.so.4.4.4


The link command (which builds a plugin):

$ gcc -shared  -fPIC -DPIC  .libs/atilibusb_la-atilibusb.o -Wl,-rpath \

-Wl,/home/mk/debian-pkg/lirc-0.9.4~pre2/lib/.libs -L../lib \

/home/mk/debian-pkg/lirc-0.9.4~pre2/lib/.libs/liblirc_driver.so \

-ludev -lusb  -pthread -g -O2 -fstack-protector-strong -Wl,-z \

-Wl,relro   -pthread -Wl,-soname -Wl,atilibusb.so -o .libs/atilibusb.so


Facts in case:

- The command is generated by autotools.

- The same package builds fine on jessie.

- If I remove the -lusb option the link succeeds, but the resulting 
plugin is of course unusable having unresolved references.

- libusb-0.1-4 and libusb-dev is in place:

$ dpkg -L libusb-0.1-4
...
/lib/x86_64-linux-gnu/libusb-0.1.so.4.4.4
/lib/x86_64-linux-gnu/libusb-0.1.so.4

dpkg -s libusb-dev
...
Version: 2:0.1.12-29


Feeling lost. The error message just makes no sense. Any hint out there?


Cheers!
