Comment (by chrisminett):

 OK, so having run them all in trace mode (I must have not done it properly
 before) they all need `pkgconfig` except `php-dba`. Given that PHP is
 moving to using pkg-config, it seems it might be sensible to add it as a
 general build dependency in the PHP portfile when the branch is gteq
 php74. I'm not sure how best to achieve this though, as the SAPI block
 uses `depends_build       port:pkgconfig`. Is it possible to just put the
 following above the SAPI if block, or should it be with `-append` ?

 {{{
 if {[vercmp ${branch} 7.4] >= 0} {
     depends_build    port:pkgconfig
 }
 }}}
