1strace: fix system call matching code in get_scno for be8 arm
2
3on ARM V7 operating in big endian mode strace does not work:
4
5root@genericarmv7ab:~# strace ls
6pid 1356 unknown syscall trap 0x000000ef
7
8it happens because ARM V7 when runs as big endian operates in be8 mode,
9where instruction are still in little endian form. Strace get_scno reads
10instructions and matches it to certain pattern, but in armeb case it needs
11to byteswap it before that.
