[qemu-aarch64-static has the same issue as qemu-arm-static.]

qemu-aarch64-static has the same issue as qemu-arm-static:

configure:25883: checking whether printf survives out-of-memory conditions
configure:26055: /nxb-bin/usr/bin/cc -o conftest -O2 -pipe -mcpu=cortex-a53  -DLIBICONV_PLUG -g -fno-strict-aliasing -mcpu=cortex-a53 -DLIBICONV_PLUG -D_THREAD_SAFE  conftest.c  >&5
configure:26058: $? = 0

***MEMORY-ERROR***: [10016]: GSlice: failed to allocate 496 bytes (alignment: 512): Cannot allocate memory


and top shows:

10016 root             2  52    0   221M 13296K     0K uwait   6   0:00   0.00% /usr/local/bin/qemu-aarch64-static ./conftest


In both cases doing a kill -9 from top of the
stuck qemu-*-static process allowed things to
continue.

"checking whether printf survives out-of-memory conditions"
and qemu-aarch64-static or qemu-arm-static just do not mix
well.
