[gentoo-mips] O2 IP32 | mips-sources fails to find ldscripts

During kernel compile ld(1) is unable to find
/usr/lib/binutils/mips-unknown-linux-gnu/2.16.1/ldscripts

I was able to compile my current kernel without problems prior to changing
to gcc 4.1.1 and rebuilding world with the -e flag, so I have a bad feeling
something was altered to make this error occur.

To get through the compile I created a link within /usr/src/linux like so:

ln -s /usr/lib/binutils/mips-unknown-linux-gnu/2.16.1/ldscripts .

However, even with the working .config that is running on my machine or the
default ip32 config, I can't get this newly compiled kernel to work. It just
hangs or does even load.


Here is the original error:

  CHK     include/linux/version.h

Hi,

The ldscripts directory that you mention is a part of the bintuils ebuild. 
Not sure why your other tools are having problems.  Here's the present 
levels of all my relevant stuff:

binutils-2.16.1-r3
binutils-config-1.9-r3
gcc-3.4.6-r1
gcc-4.1.1
gcc-config-1.3.13-r4
kgcc64-3.4.6
kgcc64-4.1.1

As I look at it, it appears that only gcc-4.1.1 and kgcc64-4.1.1 are new. 
The others all came from the mips4 stage3 tarball when I installed the 
system a few weeks ago.

When I call mips64-unknown-linux-gnu-gcc with the -v flag, it is clearly 
the 3.4.6 compiler.  So the 4.1.1 versions would appear somewhat 
irrelevant at the moment.  I built the kernel I'm running on now, and by 
appearances, it must have been the kgcc/gcc 3.4.6 that was used.  It seems 
the only way I can call the 4.1.1 compiler is by using an explicit path 
down into it's tree.

-S-

Haven't seen this one before, but I'm taking a stab and wondering if the 
-multitarget keyword is to blame.

I've never tried disabling it, but it looks like your building natively on the 
O2, so your userland/system binutils will be 32bit (mips-unknown-linux-gnu), but 
if you somehow disabled binutils from building a mips64 target (which I think it 
does during normal installs, cause they take up hardly no space), then I could 
see why the aboved referenced elf64* file is missing.

Try building w/ multitarget enabled, and see if that changes things.
