This commit bumps glibc to version 2.40. See the release notes at: https://sourceware.org/pipermail/libc-alpha/2024-July/158467.html The patches against localedef are refreshed. The patch 0003 requires a small change: the macro to tweak is no longer _ISOC2K_SOURCE, but _ISOC23_SOURCE. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
