Big-endian targets: Fix implptrpiece.exp
The test case implptrpiece.exp accesses the second byte of the short integer number 1 and expects it to be zero. This is valid for little-endian targets, but fails on big-endian targets. This is fixed by distinguishing the expected value by endianness. gdb/testsuite/ChangeLog: * gdb.dwarf2/implptrpiece.exp: Fix check for big-endian targets.
