It looks that "default_target_rtl" symbol can not be reached with GP relative

FWIW, I've never gotten that linkage failure on my alphaev6-linux machine, and
last week's snapshots (4.7-20110423, 4.6-20110422, and 4.5-20110421) all
bootstrapped fine on it.

I do have quite an old binutils (2.18.50.0.9-8.fc10 20080822).  I tried
binutils-2.21 once, but it regressed some gcc tls test so I ditched it. 
Haven't tried any other binutils versions yet.

Can you please post your configure command?

I have reported this problem to binutils and it was fixed by rth in post-2.21
SVN.

Do you have a reference, like a PR number or an approximate commit date?  I'd
like to backport this fix to my binutils 2.21 based branch.

Maybe you should also backport an unrelated alpha fix:

I am using patch from URL [1] in my builds.  While not perfect, it works OK.

Since this is linker bug, I have added rth to CC in the hope that he has better
solution.

gcc again bootstraps OK on 4.7 branch and 4.8 mainline.

With binutils-2.22 (vanilla) I'm unable to bootstrap gcc-4.6.3 on
alphaev6-unknown-linux, due to a bunch of 'relocation truncated to fit' errors.
 Applying the patch from #c12 allows gcc-4.6.3 to bootstrap, but that compiler
is unable to build a linux-3.3.0 kernel, the final vmlinux link step fails with
a bunch of 'relocation truncated to fit: GPREL16' errors .

gcc-4.4.7 + binutils-2.22 works.

It seems to be triggered(*) by Uros' PR46533 patch in r166999:
http://gcc.gnu.org/viewcvs?view=revision&revision=166999

Repeat-by:
1. have cross tools to alpha-linux hosted on e.g. x86, mine has binutils-2.20.1
2. build gcc-4.6 r166998 as cross to alpha-linux
3. used the above to cross-build a linux-3.3.0 kernel, this works for me
4. repeat steps 2 and 3 with gcc-4.6 r166999, gcc builds ok but the kernel
build fails with the usual 'relocation truncated to fit: GPREL16 against ...'
errors

In my cross environment gcc 4.7 and 4.8 also fail to build a linux kernel, but
4.5.3 and 4.4.7 work.

(*) Presumably gcc triggers a bug in ld.

I don't think that this patch has anything to do with GPREL16. The patch fixes
relocation on functions, where you have problems with symbol relocations.

Just stick -Wl,--no-relax somewhere. This is standard practice to build a
kernel.

The linker bug [1] was fixed in binutils 2.25 and GCC workaround was removed
for gcc 5.0.

This is the same issue as in PR65200.  One suggests documentation and some code
changes.  Making this as duplicate and will add documentation to the other.
