Yocto build cross toolchain issue.

Hi ,

We build cross toolchain for corei7-64 arch based processor and getting build issue with the toolchain. Toolchain reports below error while linking some static libraries,

-Wl,--end-group -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed -static -lnsl -lpthread -lm -lrt

/sysroots/corei7-64-poky-linux/usr/lib/../lib/librt.a(shm_open.o): In function `shm_open':

/build/tmp/work/corei7-64-poky-linux/glibc/2.22-r0/git/rt/../sysdeps/posix/shm_open.c:35: undefined reference to `__shm_directory'

/sysroots/corei7-64-poky-linux/usr/lib/../lib/librt.a(shm_unlink.o): In function `shm_unlink':

/build/tmp/work/corei7-64-poky-linux/glibc/2.22-r0/git/rt/../sysdeps/posix/shm_unlink.c:35: undefined reference to `__shm_directory'

collect2: error: ld returned 1 exit status

What could be the possible reason for above errors.
