Building imagemagick on macOS Intel does not include TIFF

[mpociot]

When building static PHP on macOS / Intel it seems like Imagemagick does not get compiled with TIFF included and the test/assertion fails.

On the arm build I get:

checking for libtiff-4 >= 4.0.0... yes

Which successfully enables libtiff.

On the Intel build this returns no.

However, libtiff was successfully installed on the Intel build according to the logs:

2025-01-16T20:39:22.2175100Z �[32m[20:39:22] [INFO] lib [libtiff] setup success, took 35.05 s�[0m

This problem seems to be caused by the x86_64 runner:

• The file /usr/local/lib/libzstd.a exists in the macos-13 runner, which causes the libtiff library to think it exists during the compilation process.
• When compiling imagemagick, when checking the tiff library, pkg-config detects that libtiff-4.pc depends on libzstd, but buildroot/bin/pkg-config does not find the libzstd library at this time, so it returns libtiff-4 ... no.
• As a result, the imagick extension and ImageMagick library do not contain support for libtiff.
