This is similar to commit 06537f05d4b6a0d2db01c6afda1d2a0ea2588126 to the
newlib for ARC.
GCC for ARC has been updated to provide consistent naming of preprocessor
definitions for different optional architecture features:
* __ARC_BARREL_SHIFTER__ instead of __Xbarrel_shifter for
-mbarrel-shifter
* __ARCEM__ instead of __EM__ for ARC EM cores
* __ARCHS__ instead of __HS__ for ARC HS cores
* etc (not used in libgloss)
This patch updates crt0.S for ARC to use new definitions instead of a
deprecated ones. To ensure compatibility with older compiler new definitions
are also defined in crt0.S if needed, based on presence of deprecated
preprocessor definitions.
