[oe] EABI pain and frustration!

[pspreadborough at comcast.net]

I'm working from the Angstrom distribution. 

I'm using the arm-2009q3-67-arm-none-linux-gnueabi compiler because that's 
the EABI compiler I had to hand. I started out with the intention of moving to 
an EABI environment (no OABI_COMPAT), however when my EABI ramfs did 
not work (kernel booted but barfed when executing init or sh) I decided to try 
and EABI executable in the OABI environment.

When compiling the "HelloWorld" I used the "-mabi=aapcs-linux" compiler option 
because that's what the kernel uses. 


Thanks,

Pete

hmm just tune and machine opts wont be enough you have to chose right abi 
options too. because your userland is OABI thats what you should chose for 
helloworld too.
