The version script isn't needed at compile time, only at linking time;
so you can use the -c and --symbols options together to compile to .o
files, generate the version script, but skip the linking step. After
that, you can run the ld command separately with the generated version
script and .o files.

(Another option is to use the -C option that tells vala to only compile
to C source code, and run gcc and ld yourself.)
