Subject: [PATCH] package/libsoup3: fix static build

Since the bump to 3.7.3, libsoup unconditionally includes <dlfcn.h>
in soup-init.c to detect whether libsoup2 is loaded in the same
process. Static-only toolchains such as uClibc-ng without shared
library support don't provide this header, so the build fails:

../libsoup/soup-init.c:21:10: fatal error: dlfcn.h: No such file or directory

Add a patch, submitted upstream, that checks for dlfcn.h at configure
time and skips the libsoup2 detection when it is not available.

Fixes:

Fixes: 55cec1d01307f8e93c6ce61c95c22c863fc1ce28 ("package/libsoup3: bump to 3.7.3")

+Subject: [PATCH] soup-init: only use dlopen() when dlfcn.h is available
+
+Commit 1296cbf983f0 ("soup-init: Use libdl instead of gmodule in
+`soup2_is_loaded` check") unconditionally includes <dlfcn.h> on
+non-Windows platforms. Static-only toolchains (e.g. uClibc-ng built
+without shared library support) don't provide this header, so the
+build fails:
+
+../libsoup/soup-init.c:21:10: fatal error: dlfcn.h: No such file or directory
+
+Check for dlfcn.h at configure time and skip the libsoup2 detection
+when it is not available. Without dynamic loading, libsoup2 cannot be
+loaded into the process at runtime anyway.
