Well, with a patch the build succeeds:
http://koji.fedoraproject.org/koji/taskinfo?taskID=811499
srpm is available from:
http://koji.fedoraproject.org/scratch/mtasaka/task_811499/

Without the patch,
build.logs show the difference between x86_64 and ppc like:
----------------------------------------------------------
-checking for ppc-redhat-linux-gnu-gcc... 
+checking for x86_64-redhat-linux-gnu-gcc... 
no
checking for gcc... 
gcc
@@ -130,34 +130,68 @@
checking for unistd.h... 
yes
checking for GNU Readline library, version 2.0 or newer... 
-no (it is present but too old to use)
+yes, installed version is 5.2

So by some reason libreadline.so is not found or so.
----------------------------------------------------------

I tried to print out what config.log says and it is here:
http://koji.fedoraproject.org/koji/taskinfo?taskID=811491

build.log shows:

configure: failed program was:

| 		readline(0);
| 		rl_completion_append_character(0);
| 
|   ;
|   return 0;
| }

However, in readline.h rl_completion_append_character is just "extern int"
and this is actually wrong.

Applying a patch against acinclude.m4 is needed. If you don't want to call
autoconf, modify configure directly.
