luajit: using dynamic buildmode reduces package size with about 50%

[mikma]

By using dynamic buildmode the size of the package can be reduced with about 50%. Both the ipk size and the size of the installed files.

Without patch:

# ls -l `opkg files luajit|grep /`
-rwxr-xr-x    1 root     root        405739 Dec 20 00:18 /usr/bin/luajit
