configure.ac : Pass -fno-inline-small-functions when using GCC 4.7

For some reason, the build fails when using GCC 4.7 due to the implicit
-finline-functions option passed to the compiler when -O3 is enabled,
which does not happen in newer versions of GCC, probably due to some of
the "General Optimizer Improvements" included in 4.8 (see [1]).

Fortunately, we don't need to disable -finline-functions completely but
just do it for "small functions", which is what this patch does.
