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

[Thomas De Schampheleire]

From: Thomas De Schampheleire <thomas.de_schampheleire at nokia.com>

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.
