We have a problem when for example, a glibc 2.27 based system builds some
library like libpopt-native and puts it into sstate then it is reused
on a pre glibc-2.27 system to build something which depends on popt like
rpm-native. This results in an error like:
recipe-sysroot-native/usr/lib/libpopt.so: undefined reference to `glob@GLIBC_2.27'
In the past we've had this problem with new symbols like getrandom and
getentropy, here its with a more complex symbol where there is an old
version and a newer version.
We've looked into various options, basically we cannot link against our
uninative libc/ld.so since we don't have the right headers or compiler
link libraries. The compiler doesn't allow you to switch in a new set
either, even if we did want to ship them. Shipping a complete compiler,
dev headers and libs also isn't an option.
On the other hand if we follow the ld man page, it does say:
"""
The reasons for allowing undefined symbol references in shared libraries
specified at link time are that:
- A shared library specified at link time may not be the same as the one
that is available at load time, so the symbol might actually be
resolvable at load time.
"""
which is exactly this case. By the time the binary runs, it will use
our uninative loader and libc and the symbol will be available.
Therefore we basically have a choice, we get weird intermittent bugs,
we drop uninative entirely, or we pass this option.
If we pass the option, we can drop the other workarounds too.

The patch tool will apply patches by default with "fuzz", which is where if the
hunk context isn't present but what is there is close enough, it will force the
patch in.
Whilst this is useful when there's just whitespace changes, when applied to
source it is possible for a patch applied with fuzz to produce broken code which
still compiles (see #10450). This is obviously bad.
We'd like to eventually have do_patch() rejecting any fuzz on these grounds. For
that to be realistic the existing patches with fuzz need to be rebased and
reviewed.

getrandom() is only available in glibc 2.25+ and uninative may relocate
binaries onto systems that don't have this function. For now, force
the code to the older codepath until we can come up with a better solution
for this kind of issue.
