GCC options pairs -mlittle/-mlittle-endian and -mbig/-mbig-endian are
equivalent on ppc64 architecture. However, Clang supports only long
version of the options.
Use longer form in configure to properly support both GCC and Clang
compiler. In addition, fix this issue in tcg test configure.

This is v2 of configure: Use -mlittle-endian instead of -mlittle for ppc64.
v2:
- handle both -mlittle and -mbig usage
- fix tests/tcg/configure.sh
