This lets the linker tell us what kind of alignment is required
for both tdata and tbss data when copying them into stack.
If they are not aligned as expected by the toolchain, generated
code would be accessing incorrect location for thread variables.

XCC Clang doesn't emit load address when a section
is empty, resulting in __tdata_start not being
defined. So put a #ifdef guard for the thread local
storage linker script to avoid this issue.

This adds the tdata and tbss sections required for thread local
storage. They are in ROM area as these sections are not to be
directly accessed, but copied to thread local storage area at
thread creation.
