The latter is supported in binutils for backwards compatibility, but in
general -R<path> is equivalent to --just-symbols=<path> when path
is a file; only when it's a directory, it's treated as -rpath=<path>.

Better avoid that ambiguity and use -rpath.

Also split -Wl,--enable-new-dtags and -Wl,-rpath,... into two
separate arguments, which is more common, and more likely to be parsed
correctly by compiler wrappers.

This commit does not attempt to add --enable-new-dtags to other
linkers than binutils ld/gold that support the flag.

After fixing the linter failures, there's still a test failure at distutils/tests/test_unixccompiler.py:156:
