scripts: bundle-libraries: prevent loading host locales (FS#1803)
Binary patch the bundled glibc library to inhibit loading of host locale archives in order to avoid triggering internal libc assertions when invoking shipped, bundled executables. The problem has been solved with upstream Glibc commit 0062ace229 ("Gracefully handle incompatible locale data") but we still need to deal with older Glibc binaries for some time to come. Fixes FS#1803 Signed-off-by: Jo-Philipp Wich <jo@mein.io>
