tools: Work around BITS_PER_LONG related build failure in objtool
The objtool build fails with the recent changes to the bits-per-long
headers:
tools/include/linux/bitops.h:12:0: error: "BITS_PER_LONG" redefined [-Werror]
Which got introduced by:
bb9707077b4e tools: Copy the bitsperlong.h files from the kernel
Work it around for the time being.
