ftrace: Have recordmcount honor endianness in fn_ELF_R_INFO

It looks to me like the change which introduced "virtual functions"
forgot about cross-platform endianness.

Thank you to Arnaud for supplying before+after data files do_mounts*.o.

This fixes a MIPS build failure triggered by recordmcount.
