gcc: upgrade gcc for powerpc to version 4.5.0
Fix one parameter order issue for base_contains function, which impacts glibc build under new gcc. Add new judge code to determine whether <altivec.h> is needed. This fixes the mpeg2dec build failure under new gcc. Use O2 as the optimization flag to tinylogin as it will meet segfault if compiled by gcc-4.5.0 when enable both frename-registers and Os options. Use O2 instead. Signed-off-by: Dongxiao Xu <dongxiao.xu@intel.com>

1Add new method to judge whether <altivec.h> is needed
2
3The original logic will use "typedef vector int t;" to judge
4whether <altivec.h> is needed. altivec.h contains the following
5statement:
6
7 #if !defined(__APPLE_ALTIVEC__)
8 #define vector __vector
9 #define pixel __pixel
10 #define bool
11 #endif
12
13In gcc-4.3.3, __APPLE_ALTIVEC__ is not defined by compiler, neither
14as vector, pixel, and bool. In order to make "typedef vector int t;"
15pass the compilation, we need to include altivec.h.
16
17However in gcc-4.5.0, __APPLE_ALTIVEC__ is defined by compiler,
18so as vector, pixel, and bool. We could not judge whether
19altivec.h is needed by "typedef vector int t;".
20Here we include another statement "int tmp = __CR6_EQ;", in
21which __CR6_EQ is defined in altivec.h.
