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. Fixes #32015 Signed-off-by: Daniel Leung <daniel.leung@intel.com>
