PowerPC Disassembler Fails to Compile on CentOS 7

[Joel Sherrill]

Hi

binutils hash ed29efb which should be near the head appears to be assuming
that a newer GCC is being used which defaults to something else. The host
GCC reports:

gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44)

And the compilation fails with this:

libtool: compile:  gcc -O2 -g -pipe
-I/home/joel/rtems-cron-7/rtems-source-builder/rtems/build/tmp/sb-1001/7/rtems-powerpc/home/joel/rtems-cron-7/tools/7/include

note: use option -std=c99 or -std=gnu99 to compile your code

Should the code not declare i in the for loop of the compiler arguments add
C99?
