It looks like prlimit64 is missing from libc.

$ '/tool/xilinx/gnu/microblazeel-unknown-linux-gnu/bin/microblazeel-unknown-linux-gnu-readelf' -a '/tool/xilinx/gnu/microblazeel-unknown-linux-gnu/microblazeel-unknown-linux-gnu/libc/lib/libc-2.14.90.so' | grep "prlimit"
   537: 0012a980   388 FUNC    GLOBAL DEFAULT   11 prlimit@@GLIBC_2.13
  6443: 0012a980   388 FUNC    GLOBAL DEFAULT   11 prlimit

The toolchain that I'm using is the pre-built toolchain from the xilinx microblaze-gnu.git repository. The version is 4.6.2

$ '/tool/xilinx/gnu/microblazeel-unknown-linux-gnu/bin/microblazeel-unknown-linux-gnu-gcc' -v
