M.F. 隨手記: GCC-4.6.0 arm-none-linux-gnueabi build script for both little and big endian static toolchain

1) gcc-4.6.0 with arm-none-linux-gnueabi
2) support both -mlittle-endian and -mbig-endian
3) default -mhard-float and multilib for cortex-a9
4) static-build gcc/g++

The patches to gcc-4.6.0:

# needed to fix gcc-3.2.3/glibc-2.3.2 targeting arm
#
