I tried packaging this into a .deb package for use with rebootstrap, but
ran into a couple of test failures from glibc itself, when testing the i386
version while running on an older x86_64 kernel (4.15):

which seems a bug in the test suite. The other two get a segfault
that I have not debugged, but I guess this is likely a problem in your
patches. Have you seen the same thing?
