It's failing on Debian 8, which is kernel 4.9.0:

| ../expat-2.2.2/lib/xmlparse.c:56:3: error: #error You do not have support
for any sources of high quality entropy enabled. For end user security,
that is probably not what you want. Your options include: * Linux + glibc
>=2.25 (getrandom): HAVE_GETRANDOM, * Linux + glibc <2.25 (syscall
SYS_getrandom): HAVE_SYSCALL_GETRANDOM, * BSD / macOS (arc4random_buf):
HAVE_ARC4RANDOM_BUF, * libbsd (arc4random_buf): HAVE_ARC4RANDOM_BUF +
HAVE_LIBBSD, * Windows (RtlGenRandom): _WIN32. If insist on not using any
of these, bypass this error by defining XML_POOR_ENTROPY; you have been
warned. For CMake, one way to pass the define is: cmake
-DCMAKE_C_FLAGS="-pipe -O2 -DHAVE_SYSCALL_GETRANDOM" . If you have reasons
to patch this detection code away or need changes to the build system,
please open a bug. Thank you!

I suspect the detection code is well and truly broken.
