Removed weird uclibc++ compatibility stuff as it seems to not be needed
anymore.
Switched to standard variables.
Added PKG_BUILD_PARALLEL for faster compilation.
Removed PKG_FIXUP as it seems the package has been fixed already.
A few changes to the CFLAGS and linker options resulted in ipk size going
from 244694 to 244283, possibly due to previous overlinking.
