I'm as-needed in the linker but glibc defeated that by having librt pull in
libpthread when clock_gettime() has been part of glibc proper since the 2.17
release ~7 years ago.

Meanwhile, Android seem to have reinvented the microkernel again and turned
everything in the world into message passing:

But then as far as I could tell flatpak and friends mostly exist because people
forgot about static linking. (A shared library to fake a mount point from a
statically linked zipfile could be fun, and sounds less complicated than
fakeroot or crunchgen were, but no: we have this new container infrastructure so
everything looks like a nail...)

Anyway, applied.
