 Trying to update expat -- or rather, something else that requires expat --
 but it repeatedly fails while building expat.  Looking in the log, the
 following looks like the most likely culprit:

 {{{
 :info:build 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 reaso
 ns to patch this detection code away or need changes to the build system,
 please open a bug. Thank you!
 }}}

 I don't care about having high quality entropy.  I just want to build the
 (other) thing I want to build.  (Why does an XML Parser care about this
 anyway?!)
