I have compile powerpc-utils and it doesn't fail.
Hmm, it's strange
Just want to say that current release is : powerpc-utils-1.2.26-2.el7.src.rpm and that can make the difference.
I didn't compile 1.2.26 yet (test with1.2.24-7) , but current release version also has the patch with
+ man/lsprop.8:q \
line, and I am sure it is error anyway ;)
