[U-Boot] undefined reference to `abort'

[Shadid, Bill]

This is a follow-up to my issue, re:

It was suggested that I should migrate to a newer version of u-boot to resolve the issue.

I downloaded and compiled with u-boot-2011.03-rc and the compiler reported the same errors.
We thought that maybe the rc release was not the best choice so we tried the port with u-boot 1.3.1. and again, got the same compile errors.

I did a little more digging and found that anywhere that I perform a multiply or divide operation using a float variable, the code will compile as a muldf3 or divdf3 call. So, I'm guessing that the libgcc in ELDK4.2.2 differs from that in ELDK 4.0. Is there some option I need to add to the compile expression in the Makefile to satisfy the new libgcc-floating math functions?

Thank you in advance for your assistance,
Bill.
