remove linuxthreads.new, rename linuxthreads.old
Linuxthreads.new isn't really useful with the existence of NPTL/TLS for well supported architectures. There is no reason to use LT.new for ARM/MIPS or other architectures supporting NPTL/TLS. It is not available for noMMU architectures like Blackfin or FR-V. To simplify the live of the few uClibc-ng developers, LT.new is removed and LT.old is renamed to LT. LINUXTHREADS_OLD -> UCLIBC_HAS_LINUXTHREADS

-#undef USE_TLS
-
-
-/* An architecture-specific version of this file has to defined a
- number of symbols:
-
- TLS_TCB_AT_TP or TLS_DTV_AT_TP
-
- The presence of one of these symbols signals which variant of
- the TLS ABI is used. There are in the moment two variants
- available:
-
- * the thread pointer points to a thread control block
-
- * the thread pointer points to the dynamic thread vector
-
-
- TLS_TCB_SIZE
-
- This is the size of the thread control block structure. How
- this is actually defined depends on the ABI. The thread control
- block could be internal descriptor of the thread library or
- just a data structure which allows finding the DTV.
-
- TLS_INIT_TCB_SIZE
-
- Similarly, but this value is only used at startup and in the
- dynamic linker itself. There are no threads in use at that time.
-
-
- TLS_TCB_ALIGN
-
- Alignment requirements for the TCB structure.
-
- TLS_INIT_TCB_ALIGN
-
- Similarly, but for the structure used at startup time.
-
-
- INSTALL_DTV(tcb, init_dtv)
-
- This macro must install the given initial DTV into the thread control
- block TCB. The normal runtime functionality must then be able to
- use the value.
-
-
- TLS_INIT_TP(tcb, firstcall)
-
- This macro must initialize the thread pointer to enable normal TLS
- operation. The first parameter is a pointer to the thread control
- block. The second parameter specifies whether this is the first
- call for the TCB. ld.so calls this macro more than once.
-
-
- THREAD_DTV()
-
- This macro returns the address of the DTV of the current thread.
- This normally is done using the the thread register which points
- to the dtv or the TCB (from which the DTV can found).
