[Buildroot] [PATCH 1/1] package/atf: fix build with newer gcc

[Bernd Kuhls]

Buildroot commit d6c3257e931ed256e3ebcd78938f6146bba8586f bumped the
package from 0.21 to 0.23. Upstream release 0.22 includes commit
https://github.com/freebsd/atf/commit/d7c7c53c0626ab59a62aa4efcf05323b3621baa9
which uses CLOCK_MONOTONIC without including time.h.

Fixes:

Do you have a minimal reproducer, preferably with an external
toolchain? I built atf successfully with gcc 14.x uClibc and glibc
toolchains (Bootlin toolchains). The file atf-check.cpp was built
successfully, so I'm curious to understand what makes a difference.

Thanks,

Thomas
