[ELDK] ELDK on Ubuntu 11.10

[krish]

Hi Johan,

I have installed eldk-5.0 with the steps provided by you.

The cross compilers are present in following path:
/opt/eldk-5.0/powerpc/sysroots/i686-oesdk-linux/usr/bin/powerpc-linux/

Add above cross compiler path to $PATH and use "powerpc-linux-gcc" to
compile your programs.

There is no "ppc_85xx-" in eldk-5.0.

"/opt/eldk-5.0/powerpc/rootfs/usr/bin/gcc" is if type "ELF 32-bit MSB
executable, PowerPC or cisco 4500". It means this can be executed on big
endian systems.
