[uClibc] toolchain: ppc assembler error ( .section ".relocate_code", "xa") when compiling linux 2.6.1 kernel???

[Ken McGuire]

I have had the same problem with both toolchain 2.95 and 3.3x from uClibc.org

It appears to be a binutils issue,  /toolchain/gcc-3.3.x/make/binutils-uclibc.mk and
/toolchain/gcc-2.95/make/binutils-uclibc.mk were regressed from
BINUTILS_DIR:=$(TOOL_BUILD_DIR)/binutils-2.14.90.0.7 to
BINUTILS_DIR:=$(TOOL_BUILD_DIR)/binutils-2.14.90.0.6 to fix building for
arm, I  think that 2.14.90.0.5 worked with ppc, and there are comments in binutils
2.14.90.0.7 &.8 changelogs implying that some ppc issues were fixed, but .6 results in the uitl.S issue.

I found these references to the problen which (I believe) explains the issue (better than I can).

http://sources.redhat.com/ml/binutils/2003-09/msg00380.html  and 
http://sources.redhat.com/ml/binutils/2003-09/msg00381.html

This applies to kernel versions 2.4.18 and above as well as the 2.6 series. The util.S
code appeared somewhere between 2.4.18pre6 and 2.4.18.

The 3.4.x toolchain uses bunutils 2.15.91.0.1 (when I tried it, but now uses
2.15.91.0.3) and I haven't gotten past an initial error due to stdargs.h not being found.
 I think somehow my 3.4.x toolchain wasn't built properly, but I haven't figured out why yet.
