seems to be x86 related. ARM verson compiles without errors.

I have taken your exact configuration, and didn't manage to reproduce the bug.
By any chance, did you make manual modifications to the uClibc configuration by
running make uclibc-menuconfig? If you've done so and disabled
UCLIBC_HAS_REALTIME, then mq_getattr would not be available in the C library,
leading to the error you got.

Can you get back to us and confirm which uClibc you had? Thanks!

Actually I've encountered this too but building on Gentoo using Portage rather
than Buildroot. My target is i586-pc-linux-uclibc and I have definitely enabled
UCLIBC_HAS_REALTIME. I've checked and mq_getsetattr.c, where this function is
defined, definitely gets built but for some reason, the symbol is missing from
librt. I haven't yet managed to work out why.

Aha! Found the cause and it turns out this is a Linux bug that has already been
fixed.
