# glibc 2.33 compat fix: if `has_statx = true` is set, `tools/virtiofsd/passthrough_ll.c` will
# rely on `stx_mnt_id`[1] which is not part of glibc's `statx`-struct definition.
#
# `has_statx` will be set to `true` if a simple C program which uses a few `statx`
# consts & struct fields successfully compiles. It seems as this only builds on glibc-2.33
# since most likely[2] and because of that, the problematic code-path will be used.
