__JMP_BUF_SP is the index of a stack pointer slot in the __jmp_buf. According to ARM __sigsetjmp code it does not depend on configuration parameter __UCLIBC_HAS_FPU__. Make its definition unconditional. __JMP_BUF_SP is used in the unwind_stop through the _JMPBUF_CFA_UNWINDS_ADJ macro, this change fixes cleanup routines call on thread cancellation in configurations with hard FP.
