GNU linker: alternative to --version-script to list exported symbols at the command line?

Question

On Linux with the GNU toolchain, I know how to control exported symbols from a shared library with a version script (gcc -Wl,--version-script=symbols.map), but I would like to list exported symbols on the command line instead. IOW, I would like the equivalent of

link /EXPORT:foo 

from the MS toolchain. Is it possible ?

EDIT:

My question may not be very clearn: if I have a library libfoo.so, and I want to only export libraries foo1 and foo2, I can go create a version script foo.linux as follows

libfoo.so
{
global:
    foo1;
    foo2;
local:
    *;
}

And do

gcc -shared foo.c -Wl,--version-script=foo.linux -o libfoo.so -soname libfoo.so

I would like to be able to do something like this instead:

gcc -shared foo.c -Wl,--export-symbol=foo1 -Wl,--export-symbol=foo2 -o libfoo.so -soname libfoo.so

I'm not sure that you can do this like you want. One way is with the linker version script like you mentioned. Another way is to add in your source code __attribute__ ((visibility("default"))) for whatever you want exported and compile everything with -fvisibility=hidden
