Josh Poimboeuf 55149d0653 objtool, compiler.h: Fix __unreachable section relocation size
Linus reported the following commit broke module loading on his laptop:

  d1091c7fa3 ("objtool: Improve detection of BUG() and other dead ends")

It showed errors like the following:

  module: overflow in relocation type 10 val ffffffffc02afc81
  module: 'nvme' likely not compiled with -mcmodel=kernel

The problem is that the __unreachable section addresses are stored using
the '.long' asm directive, which isn't big enough for .text section
kernel addresses.  Use relative addresses instead:

  ".long %c0b - .\t\n"
