I don't think it's glibc, here make compiles fine:

$ eix -I make
...
sys-devel/make
     Installed versions:  4.2.1-r1(06:56:41 PM 12/11/2017)(nls -guile -static)

$ eix -I glibc
...
Installed versions:  2.26-r3(2.2)^s(07:08:24 PM 12/04/2017)(-audit -caps -debug -gd
-hardened -multilib -nscd -profile -selinux -suid -systemtap -vanilla
CROSSCOMPILE_OPTS="-headers-only")

...but:

$ grep _GNU_GLOB_INTERFACE_VERSION /usr/include/gnu-versions.h
#define _GNU_GLOB_INTERFACE_VERSION	1 /* vs posix/glob.c */
