No. The cause is a few lines above that:

UNAME_MACHINE = ppc64le
UNAME_RELEASE = 3.10.0-514.10.2.el7.ppc64le
UNAME_SYSTEM  = Linux
UNAME_VERSION = #1 SMP Fri Mar 3 16:16:38 GMT 2017
child process exited abnormally
    while executing
[...]
make[2]: *** [jim/libjim.a] Error 1
make[2]: *** Waiting for unfinished jobs....
