This is largely (and on many platforms, entirely) a function of the
linker, not the compiler per se.  The compiler driver ("gcc" or "g++",
etc) can pass arbitrary (comma-separated) options to the linker with -Wl,
so you need to read the man page for the linker you're using[*], figure out
which options to pass to it, and then feed those to gcc/g++.  For example,
on Solaris it's something like

    gcc a.o b.o ... z.o -Wl,-B,static -lfoo -Wl,-B,dynamic -lbar

and the linker receives

    ld ..... -B static -lfoo -B dynamic -lbar ....
