Sure, but the ``correct'' method depends on the platform (which you 
should have mentioned).   For all Unix & Unix-like OSes I'm familiar with
*except* AIX, if the libraries depend on each other, then the library you
list first needs to also appear (again) after the library that depends on
it, like:

	-lb1 -lb2 -lb1

Most `ld's work from left to right (AIX's doesn't), so symbols missing from
`libb1.a' that are present in `libb2.a' will be taken care of with the first
two `-l' statements.  Then, symbols missing `libb2.a' that are present in
`libb1.a' will be taken care of by the second two `-l' statements.

Alternately, you could extract the necessary .o files and create a third
library from the .o files that has everything you need.
