Hi,
I have played with an upgrade to gcc-4.6.2 as target-compiler for
MIPSel in a OSS router project called Freetz [1].
Unfortunately, the build of ltrace-0.5.3 failed like this:
/mnt/sdb3/freetz/freetz-trunk/toolchain/build/mipsel_gcc-4.6.2_uClibc-0.9.32/mipsel-linux-uclibc/bin/mipsel-linux-uclibc-gcc
main.o libltrace.a -lelf -lsupc++ -liberty -o ltrace
/mnt/sdb3/freetz/freetz-trunk/toolchain/build/mipsel_gcc-4.6.2_uClibc-0.9.32/mipsel-linux-uclibc/lib/gcc/mipsel-linux-uclibc/4.6.2/../../../../mipsel-linux-uclibc/bin/ld:
skipping incompatible

when searching for -liberty
Attached is a patch of mine.
My box is running stable for more than 24hrs and ltrace works fine.
The responsible developers checked in a more robust patch in [2].
Personally, I am on Debian/sid i386, but I have not checked with
building an i386 package.
I hope one of those patches from the Freetz project is helpful to you.

P.S.: NOTE: The cause for this due to that ChangeLog entry.
