A full build log is available there: 
http://aws-logs.debian.net/2018/02/07/glibc-exp/kbuild_0.1.9998svn3127+dfsg-1_unstable_glibc-exp.log

The problem is that the glibc 2.27 slightly changed its internal glob
implementation. kbuild uses an internal copy of make, which detects that
it doesn't support the new interface and switch to its internal
implementation which is slightly broken.

The same kind of patch as for make-dfsg should probably be applied:
