commit: https://git.buildroot.net/buildroot/commit/?id=0c52826291d1884db0f8f35130216065fbc7b574
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

libblockdev is a C library supporting GObject introspection for
manipulation of block devices. It has a plugin-based architecture
where each technology (like LVM, Btrfs, MD RAID, Swap,...) is
implemented in a separate plugin, possibly with multiple
implementations.

gobject-introspection is not a strict dependency and may be disabled
via a configure flag.

This is the base package with everything disabled, the subsequent
patches in this series will add more options necessary to bump udisks
to the latest.

+Subject: [PATCH] Provide replacement function for strerror_l()
+
+strerror_l() is not implemented in some C libraries, such as uClibc,
+so let's provide a simple replacement function that falls back on
+strerror().
