Here is an example:
trippels@gcc2-power8 linux % objdump -h lib/lib.a | sed -ne
'/___ksymtab/{s/.*+/EXTERN(/;s/ .*/)/;p}' >|lib/.lib-ksyms.o.lds
trippels@gcc2-power8 linux % cat lib/.lib-ksyms.o.lds
EXTERN(argv_free)
EXTERN(argv_split)
... <The actual list goes on>
trippels@gcc2-power8 linux % ar rcsD lib/.lib_exports.o
trippels@gcc2-power8 linux % ld.bfd -r -o lib/lib-ksyms.o -T
lib/.lib-ksyms.o.lds lib/.lib_exports.o
trippels@gcc2-power8 linux % eu-readelf -a lib/lib-ksyms.o
