Dear maintainers,
libcamera fails to build from source on 32-bit architectures under 64-bit
time_t, because it has a module that legitimately un-sets _FILE_OFFSET_BITS
for building but this is not allowed without also unsetting _TIME_BITS:

(https://launchpad.net/ubuntu/+source/libcamera/0.2.0-1ubuntu3/+build/27902670)
Since this is a legitimate un-setting of _FILE_OFFSET_BITS in order to get
access to the necessary libc6 prototypes and macros, and since the functions
being intercepted are not sensitive to time_t, the simplest solution is to
also unset _TIME_BITS.
Please see the attached patch, which has been uploaded to Ubuntu to fix this
build failure.
Thanks for considering,

+Description: 64-bit time_t compatibility for v4l2 module
+ The v4l2 build unsets _FILE_OFFSET_BITS, which is not allowed when setting
+ _TIME_BITS=64. Having verified that nothing in this module is sensitive to
+ 64-bit time_t (none of the functions it intercepts handle time), we also
+ unset _TIME_BITS to allow this to build as before.
