Using '>=' is definitely not the right fix -- see the comment right above the change in the file and discussion in #31025.

According to https://autotools.io/pkgconfig/pkg_check_modules.html you shouldn't use == but =. And it is indeed correct here

fbissey@equinoxe ~ $ pkg-config --exists --print-errors "libzip = 1.7"
Requested 'libzip = 1.7' but version of libzip is 1.7.3
fbissey@equinoxe ~ $ pkg-config --exists --print-errors "libzip == 1.7"
Unknown version comparison operator '==' after package name 'libzip' in file '(command line arguments)'

For me fplll = 5.4.0 works, but not fplll = 5.4.
