I've noticed the difference between your log and my log.

Your first log file:

checking for FONTCONFIG... no
checking for ICU... no
checking for powerpc-linux-icu-config... no
checking for icu-config... icu-config
configure: WARNING: using cross tools not prefixed with host triplet
checking for ICU by using icu-config fallback... yes
checking for FREETYPE... yes
[...snip...]
Unicode callbacks (you want at least one):
        Glib:                   true
        ICU:                    true
        UCDN:                   true

My log file:

checking for FONTCONFIG... no
checking for ICU... no
checking for powerpc-linux-icu-config... no
checking for icu-config... no
checking for ICU by using icu-config fallback... no
checking for FREETYPE... yes
[...snip...]
Unicode callbacks (you want at least one):
        Glib:                   true
        ICU:                    false
        UCDN:                   true

Maybe the issue is to use ICU of CentOS system.

I've created a patch.

If this patch solves the issue, I will send the pull request.
