>=2.6.17-rc4-mm1 kernel compilation problem (relocation truncated to fit)

>=2.6.17-rc4-mm1 kernel compilation problem (relocation truncated to fit)

[Nathan Pilatzke]

I am getting compilation errors for 2.6.17-rc5-mm1 all the way back to
2.6.17-rc4-mm1.  Kernel 2.6.17-rc3-mm1 compiles better for me (I get the
undefined reference to __udivdi3 error that has been reported
previously).  Here are the errors that I get for 2.6.17-rc5-mm1:

I assume that the errors I am seeing are regarding the klibc changes
that went into 2.6.17-rc4-mm1 (and apparently no one else is seeing
these errors as I would think that I would have found them reported
somewhere).  I am running a gentoo system on an eMac 7450 PowerPC.
Here's my gcc info:

Need anything else?  Can anyone offer some help or ideas?
Thanks, nathanp.

Could you try the following patch?

Applied the patch, did a 'make clean' and 'make'.  The patch had no
effect for me, exact same errors.
