This means you have no actual elf.h with AT_TIMEKEEP installed in your
system required to build the recent libc. When you build libc, make
searches for AT_TIMEKEEP in the installed headers, and not in /usr/src.
Canonically you would need to rebuild all the world to properly build the
libc part. To not do this you could try instead (AFAIK) 'make toolchain'.
