3Bug confirmed. When code is compiled with -fstack-protector{,-all},
4GCC "emits extra code to check for buffer overflows, such as stack
5smashing attacks". This extra code uses symbols from libssp, and
6therefore (at least) Cygwin's GCC specs contain:
7
8*link_ssp:
9%{fstack-protector|fstack-protector-all:-lssp_nonshared -lssp}
10
11Therefore, when libtool fails to pass -fstack-protector{,-all} at link
12stage, the link fails.

14Patch attached. (Yes, I have a copyright assignment on file.)

23
24* libltdl/config/ltmain.m4sh (func_mode_link): Pass -fstack-protector*
25to the linker as it is required at link time to resolve libssp symbols.
