The symbol versioning tests mix C-visible symbols and linker-visible
symbols in order to verify .symver behavior. This works for most
people, but fail for targets that have a symbol prefix. So add a
helper file with macros that expand gcc's __USER_LABEL_PREFIX__ as
necessary and convert all .symver users over to it.
Now that the tests are usable on prefixed targets, update the tests
to take into account an optional leading underscore.

The example version script in the manual currently suggests:
extern "C++" { "int f(int, double)"; }
But a C++ function like that doesn't encode the return type into the
mangled name, so when the linker demangles things, it ends up with
"f(int, double)" and so it never matches.
The example also lacks a trailing semicolon after the brace, so the
linker always complains about a syntax error in the file.
While the language section documents the possibilities, it isn't clear
as to which is the default language. So explicitly state that the C
language is the default.
