I got it to build by adding --with-icu-dir=<blah> to the configure command. Nothing else changed on the system, and PHP 7.2.15 builds correctly without this configuration change.

I also upgraded the system to ICU 63.1, but I don't believe that was the issue.

I examined the Change Log, but could not identify a change that might have affected this in PHP 7.2.16.

FYI: The more recent versions of icu4c require c++11 as stated in "delegating constructors are permitted only in C++11".
Just add "-std=c++11" to the CXXFLAGS variable.
As in your case:
CXXFLAGS="-std=c++11" ./configure --mandir=/usr/local/share/man --enable-mbstring --enable-intl --enable-zip --enable-pcntl --enable-exif --with-libedit --with-zlib --with-bz2 --with-libzip=/usr/local --with-gd --with-webp-dir=/usr/local --with-openssl --with-curl --with-sqlite3=/usr/local --with-pdo-sqlite=/usr/local --with-mysqli --with-pdo-mysql --disable-phpdbg --enable-fpm --with-fpm-user=www --with-fpm-group=www
