I've managed to reproduce this in buildroot with the latest uclibc snapshot.

It seems to be toolchain-related, the table goes:
gcc 4.9.2 + binutils 2.25 + uclibc 0.9.33.2 = good
gcc 4.9.2 + binutils 2.25 + uclibc snapshot = bad
gcc 4.7.4 + binutils 2.22 + both uclibc versions = good

I'll try to get more details, but i suspect gcc is at fault here.
Sergiy: which gcc version are you using?
(BTW, in BR we build uclibc in ARM mode, EABI mandates interworking and
trying to build it in THUMB mode fails because of register exhaustion,
haven't tried with snapshot).
