Starting with commit 61562f981e92 "uapi: export all arch specifics
directories", a "make INSTALL_HDR_PATH=$root/usr headers_install"
operation will delete standard glibc headers and others in
$root/usr/include.

Here's the snippet from the build process where it deletes system
headers with this commit:

Reverting commit 61562f981e92 fixes the problem for me.
