Ah, thanks!  Then this is completely different to Windows.

It's only about the mandatory extensions, i.e. those you get with
./configure --disable-all (date, hash, json, pcre, random, reflection,
spl and standard).  The idea is to be able to have a minimal PHP build
without the need to install any libraries (except, of course, libc and
such).

ext/gd is a different thing; the bundled libgd is only there for BC
reasons (and should have been unbundled years ago, but hasn't due to
missing ZMM support in libgd); on most systems you usually build against
a system libgd, though.
