configure: vulkan detection not enforcing minimum version

On my system, I currently have:

pkg-config --modversion vulkan

which doesn't meet the minimum requirements in configure of 1.3.255 (i.e. my header version is 239):

if enabled vulkan; then
    check_pkg_config_header_only vulkan "vulkan >= 1.3.255" "vulkan/vulkan.h" "defined VK_VERSION_1_3" ||
        check_cpp_condition vulkan "vulkan/vulkan.h" "defined(VK_VERSION_1_4) || (defined(VK_VERSION_1_3) && VK_HEADER_VERSION >= 255)"

Unsuprisingly, the build fails on:

but this shouldn't have been attempted in the first place.

Moreover, passing --disable-vulkan doesn't avoid this issue either as it will still try to build the vulkan hwaccels + filters etc.
