This patch is a one line change to use the PTR_REG macro in a cmp instruction
in dl-tlsdesc.S.  It only causes a problem in ILP32 mode but I would like
to submit it and check it in now so that the source code is consistent in
its use of PTR_REG.  Tested in ILP32 and LP64 modes on aarch64.

I think this counts as an 'obvious' fix, so I will check it in later today
if there are no objections.
