Doesn't the GCC frontend do all this automatically? collect2 generates
an export file and adds it to the linker command, and -brtl is added
automatically, when -shared is used. The frontend does not add -G
automatically when linking shared libraries, however. On the other hand
this doesn't seem to make a difference.
