Cross makepkg

Durning works on my Master Thesis i've create port of makepkg script from ArchLinux distro. I've called it cmakepkg. Now it can compile and build packages for diffrent architecture using installed cross compiler. Using this tool i've successfully build several packages for powerpc architecture.

cmakepkg additional features:
- saving man, include files are now configurable
- config file stored in ~/.config/cmakepkg/
- configurable target platform
- configurable development envirnoment and path to it

Previously i've prepare PKGBUILD'd for cross powerpc development envirnoment, which contains:
- binutils
- gcc and g++
- glibc
