Increasing the minimum kernel headers version globally in glibc is easy
(just change LIBC_LINUX_VERSION in sysdeps/unix/sysv/linux/configure.ac).
It's also probably less controversial than increasing the minimum runtime
version (we require 3.2 or later headers unconditionally, but still allow
2.6.32 kernels at runtime on x86_64 and x86).
Increasing the minimum just for architectures that currently have 32-bit
time_t, without changing the runtime minimum, would be trickier.
