You will have the overhead of one additional archiving step (ar +
ranlib) and, on systems where one cannot pass whole archives to the
linker to put in shared libraries (e.g., -Wl,--whole-archive with GNU
ld), libtool will also extract that convenience archive one by one
again.

Hmm.  Not sure what to recommend here.  You can read the Libtool manual,
after reading this nice (if not a bit old) book:
