cpp: use -nostlib++ instead of -nostlib for custom cpp_stdlib
The <lang>_stdlib can be used in cross files to use a custom standard library
for a given language.
When cpp_stdlib is used in a cross file, meson passes
* -nostdinc++ to the compiler
* -nostlib to the linker
According to [1] (gcc) and [2] (clang), we should pass -nostlib++ to the linker
when we don't want to link to the standard C++ library.
Currently, we pass -nostlib.
Fix this by implementing a C++ specific get_no_stdlib_link_args() function.
