[bug report] frv-elf-ld relocation error

Hi:

Recently it seems that i encountered a linker bug during my work on a
FRV processor. Here is my toolchains version:
 - binutils-2.13
 - gcc-core-3.4.0

And i use the following commands to build my frv-elf toolchain from the source
packages:

 - binutils-2.13:
 configure --prefix=/usr/local/frv-elf-toolch --target=frv-elf

 - gcc-core-3.4.0:
 configure --prefix=/usr/local/frv-elf-toolch \
          --target=frv-elf --without-headers --with-newlib \
          --disable-shared --disable-threads --enable-languages=c

This relocation bug is a little hidden, it seems that it only appears when
linking a very large program. In my test case, there is a const string in
frv-linux-2.6.4/init/version.c:

   const char *linux_banner = "Linux version 2.6.4 ...";

By disassembly analysis, we can kown the address in the '.rodata' section of the
string "Linux version 2.6.4 ..." is 0xd299c. While the value of the pointer
variable 'linux_banner' is 0xd29a0. So if i use the following function to print
this string:

   printk(linux_banner);

i alway get the string "x version 2.6.4 ..." on my virtual terminal !!!

About my test case:
-------------------------

My test case is too large to be sent as an attachment. You can go to
this URL to download my test case:
http://jtager.sourceforge.net/frv-linux-2.6.4.tar.gz

Use the following command to unpack it:

   tar zxvf frv-linux-2.6.4.tar.gz

Then use the following commands to compile the source codes:

   cd frv-linux-2.6.4
   make zImage
