With this fix, sparc links vmlinuz again using crosstool. Without this
fix, the final link fails missing several dozen dozen symbols, beginning
with:
kernel/built-in.o(.text+0x6fd0): In function `do_exit':
: undefined reference to `exit_io_context'
(exit_io_context is defined in block/ll_rw_blk.c).
