I added --disable-pie to BLUEZ_UTILS_CONF_OPTS and bluez_utils build fine with
this toolchain. So it seems that PIE is not supported on microblaze.

Also I backported binutils upstream patch
47993b4af18c6ef1cad300f6393bf896d3cb5e5c but I'm not sure it's required to fix
this issue.

iproute2 build fine without NPTL support, tested with
http://autobuild.buildroot.net/toolchains/configs/br-m68k-68040-full.config

I'll send a patch.
