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!
