Support of ==

[pengyu]

The following code does not work. Can it be fixed?

$ cat a.awk
function f(x) {
    return x == "a"
}
{ print $0, f($0) }
$ awka -f  a.awk  > a.c
$ gcc -lawka a.c
Undefined symbols for architecture x86_64:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

The issue is the libawka library is not being found by the linker (or not matched to the x86_64 architecture).
