Shared libs libzimpl-pic.so and libzimpl.so are broken: they don't contain symbols from xlpglue.c like xlp_conname_exists

$ nm ./work/.build/lib/libzimpl-pic.so | grep " U " | grep xlp
                 U xlp_addcon_term
                 U xlp_addsos_term
                 U xlp_addtoobj
                 U xlp_addvar
                 U xlp_alloc
                 U xlp_conname_exists
                 U xlp_free
                 U xlp_getclass
                 U xlp_getlower
