[OE-core] [PATCH 1/1] glibc: refresh patch to also fix qemuppc

[Chen Qi]

The patch 0031-sysdeps-ieee754-prevent-maybe-uninitialized-errors.patch
did not take into consideration of qemuppc. Refresh it to also fix
building for qemuppc.

The related error message is like below:

  ../sysdeps/ieee754/ldbl-128ibm/e_jnl.c:153:20: error: 'temp' may be used uninitialized in this function [-Werror=maybe-uninitialized]
