../gtk-4.14.4/gtk/roaring/roaring.h:260:18: error: implicit declaration of function ‘_mm_popcnt_u64’; did you mean ‘_mm_popcnt_u32’? [-Wimplicit-function-declaration] - time64 systems

This bug was found using the new glibc time64 support for x86 but will effect all 32bit distros as it becomes more widely adopted.

Steps to reproduce

1.Create a glibc-time64 install (Gentoo provides stage3 files here 2. emerge --verbose --ask gui-libs/gtk

Note: Gentoo provides up to 4.14.4 but I have tested with 4.16.5 to see the issue still exists before reporting.
