Please - do not do this!  GCC knows a great deal about how to invoke
ld; if you need to pass extra options it will let you do that too.
Most of the frequently reported bugs involving dynamic symbols, shared
libraries, et cetera are cured by letting the GCC driver do its work.

You will get marginally better performance if the compiler does this
rather than a version script.
