scripts/recordmcount.pl: support big endian for ARCH sh 

The kernel test robot reported the following issue:

    CC [M]  drivers/soc/litex/litex_soc_ctrl.o
  sh4-linux-objcopy: Unable to change endianness of input file(s)
  sh4-linux-ld: cannot find drivers/soc/litex/.tmp_gl_litex_soc_ctrl.o: No such file or directory
  sh4-linux-objcopy: 'drivers/soc/litex/.tmp_mx_litex_soc_ctrl.o': No such file

The problem is that the format of input file is elf32-shbig-linux, but
sh4-linux-objcopy wants to output a file which format is elf32-sh-linux:

  $ sh4-linux-objdump -d drivers/soc/litex/litex_soc_ctrl.o | grep format
  drivers/soc/litex/litex_soc_ctrl.o:     file format elf32-shbig-linux
