aufs: Updated (3.4-20130325 -> 3.10-20130916)

As master is already having all fixes and integration for aufs
with kernels >= 3.7 we should actually update the package to
the corresponding kernel patch.
Remove .gitattributes because some patches need mixed eol
musl: fix lzo and lzop support
gcc: introduce GNU99 flag to hardcode -std=gnu99
ecore: flag as GNU99
