[dunfell][PATCH] core: glib-2.0: fix requested libmount/mkostemp/selinux not being linked in

[Ahmad Fatoum]

Since 010202076760 ("meson.bbclass: avoid unexpected operating-system
names"), meson is no longer used with a cross file that appends the used
libc to the operating system name, e.g. linux-gnueabi.

Prior to that commit, the host_system == 'linux' checks in glib's meson
failed, which led to glib being compiled without libmount, mkostemp and
selinux even if explicitly requested.

As the aforementioned commit affects all recipes built by glib, it might
not be a candidate for backporting to current stable branches. To fix
just the glib issue, instances of host_system == 'linux' are patched
locally.

The patch is marked as Upstream-Status: Inappropriate as it is rendered
unnecessary for OE releases newer than Dunfell.

+Subject: [PATCH] meson.build: do not hardcode 'linux' as the host system
+
+OE build system can set this to other values that include 'linux',
+e.g. 'linux-gnueabi'. This led to glib always being built without
+libmount, mkostemp and selinux support.
