objtool: Use target file endianness instead of a compiled constant
Some architectures like powerpc support both endianness, it's
therefore not possible to fix the endianness via arch/endianness.h
because there is no easy way to get the target endianness at
build time.
Use the endianness recorded in the file objtool is working on.
