[Buildroot] [git commit] package/pugixml: force-enable 'long long' support to support gcc<4.8

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=189c63f276fa98ef3a59b6762d87cbe0cd9974ea
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Although pugixml will enable 'long long' support automatically if it detects
C++11 (gcc 4.8+), we would like to support older gcc compilers too.
