Log:
  devel/llvm10: really fix the AT_EXECPATH fallback =(
  
  It turns out that I made not one but *two* mistakes in applying this patch
  from the version that I had sent upstream. This one is not an extra
  semicolon, but rather not dereferencing p... p may never hit AT_NULL, but *p
  certainly will.
  
  The problem was isolated and the fix identified + tested by Andrew Gierth.
