rBb9c37608a9e959a896f5358d4ab3d3d001a70833 moved evaluation of `versions.cmake` before `options.cmake`, as a result of which `BLENDER_PLATFORM_ARM` was no longer defined in `versions.cmake`, causing it to choose the wrong OpenSSL version for aarch64. This reverts that. Also fixes a compiler crash when building flex with some glibc versions. Differential Revision: https://developer.blender.org/D15319
