OK. I may have an idea. The parameters CONFIG_LIBDWARF_DIR and
CONFIG_LIBUNWIND_DIR are empty (default value). So the variable
LDFLAGS stored into .config-detected contains things like
"-L/lib" and your /lib directory contains 32bit binaries.

Could you send me the files .config and .config-detected which were
generated during the build?

I will send a new patch set.

* FYI, so far, I tested the build:
* on my archlinux x86_64 system
* and with many cross-toolchains (powerpc, arm, etc.) generated by
  crosstool-ng

I should have tested on other distros especially fedora... Sorry.

Thank you very much for testing it!

Alexis.
