Subject: clang.bbclass: create lld symbolic link in sysroot when ld-is-lld is
 set

Create a symbolic link lld -> ld in recipe sysroot to choose the
default linker lld when ld-is-lld is set in DISTRO_FEATURES. othereise,
we can get linking issues when '-fuse-ld=lld' is in LDFLAGS but the
actual ld is not lld.
