So it got installed under /usr/local

61 is ICU's major version number.
You have two ICU versions installed, one from Fedora, with
its icu*.pc config files located in usr/lib64/pkgconfig, the other
(presumably v61, as it's the latest) in /usr/local/lib/pkgconfig/
Without specifying which one should be used, it looks like
Postgres get them mixed between compilation and link.

To use self-compiled ICU, I've been having success
configuring postgres with:

PKG_CONFIG_PATH=/path/to/icu/lib/pkgconfig \
./configure --with-icu [other flags]

I tend to install ICUs versions into their own directories rather
than /usr/local, and use Debian rather than Fedora, but you
might try PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
