Patch added by commit eee96b0f0ad224b3e09a9b98c26d056e18f17fd5 on gcc
9.3.0 must also be applied on gcc 10 and 11 to avoid the following build
failure on numerous packages (babeltrace2, pcsc-lite, tpm2-pkcs11,
etc.):

configure:13774: checking whether pthreads work with -pthread
configure:13868: /home/giuliobenetti/autobuild/run/instance-0/output-1/host/bin/or1k-linux-gcc -o conftest -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64  -Os -g2  -std=gnu99 -pthread -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64  conftest.c   >&5
conftest.c:27:26: error: #error "_REENTRANT must be defined"
   27 | #                        error "_REENTRANT must be defined"
      |                          ^~~~~

It should be noted that external bootlins will have to be rebuilt.

+
+The detection of pthread support fails on OpenRISC unless _REENTRANT
+is defined. Added the CPP_SPEC definition to correct this.
