objtool: Use target file class size instead of a compiled constant
In order to allow using objtool on cross-built kernels,
determine size of long from elf data instead of using
sizeof(long) at build time.
For the time being this covers only mcount.
[Sathvika Vasireddy: Rename variable "size" to "addrsize" and function
"elf_class_size()" to "elf_class_addrsize()", and modify
create_mcount_loc_sections() function to follow reverse christmas tree
format to order local variable declarations.]
