7.3.8 LTLIBOBJS and LTALLOCA

Where an ordinary library might include ‘$(LIBOBJS)’ or ‘$(ALLOCA)’ (see LIBOBJS), a libtool library must use ‘$(LTLIBOBJS)’ or ‘$(LTALLOCA)’. This is required because the object files that libtool operates on do not necessarily end in .o.

Nowadays, the computation of LTLIBOBJS from LIBOBJS is performed automatically by Autoconf (see AC_LIBOBJ vs LIBOBJS).
