In case the LEON3FT back-to-back store workaround is active
(sparc_fix_b2bst), then define the builtin define __FIX_LEON3FT_B2BST on
RTEMS.  The intended use case for this is operating system code in
assembly language.  See also:

gcc/
	*  gcc/config/sparc/rtemself.h (TARGET_OS_CPP_BUILTINS): Add
	conditional builtin define __FIX_LEON3FT_B2BST.
