Hi All,

I got a chance to test my kern gcov path in an alpha machine.
I found a problem in ldscript.alpha. It only generates one section
with RWE flag. I tried to use the script to ld kmod. It is failed to
load for the error "too few section".

Any reason for this behavir? Or this is a bug?

Thanks,

Jun Su
