sys-devel/lld-toolchain-symlinks: New package for binutils-free sys

New package that installs generic "ld" symlink to LLD, for use
on binutils-free systems.  Note that while LLD itself is not slotted,
this package is as it installs symlinks into slotted LLVM directories
to avoid colliding with binutils-config.
