The reason is Debian Bug #871470:
The `freetype-config' script is no longer installed by default
(Closes: #871470, #886461). All packages depending on libfreetype6-dev should use pkg-config to find the relevant CFLAGS and libraries.
This problem is fixed in PHP 7.4 (php/php-src#3632) but the older versions need to be patched (see freetype.patch from Archlinux).
Also, there's a file named 0047-Use-pkg-config-for-FreeType2-detection.patch in Ondřej Surý's builds for PHP which would probably solve the problem as well (not sure how to reference it).
