ARM: 9289/1: Allow pre-ARMv5 builds with ld.lld 16.0.0 and newer
Commit 6a7ee50f8f56 ("ARM: disallow pre-ARMv5 builds with ld.lld")
prevented v4 or v4t kernels when ld.lld will link the kernel due to
inserting unsupported blx instructions.
ld.lld has been fixed in current main (16.0.0) to avoid inserting these
instructions by inserting position independent thunks instead. Allow
these configurations to be enabled when ld.lld 16.0.0 is used to link
the kernel.
Additionally, add a link to the upstream LLVM issue so that the reason
for this dependency is clearly documented.
