Applied to master, thank you!

@Fabrice, while testing this patch with utils/test-pkg I noticed 
package/librsvg (pulled in as dependency of libgtk4) fails to build 
using bootlin-x86-64-musl toolchain with introspection enabled. Maybe 
you could look into that?

Command:
./utils/test-pkg -T bootlin-x86-64-musl -c libgtk4.config

libgtk4.config:
BR2_PACKAGE_PYTHON3=y
BR2_PACKAGE_GOBJECT_INTROSPECTION=y
BR2_PACKAGE_MESA3D=y
BR2_PACKAGE_MESA3D_GALLIUM_DRIVER_SOFTPIPE=y
BR2_PACKAGE_MESA3D_OPENGL_EGL=y
BR2_PACKAGE_LIBGLVND=y
BR2_PACKAGE_LIBGLVND_DISPATCH_EGL=y
BR2_PACKAGE_LIBGTK4=y

Error:
   CCLD     rsvg-convert
   GISCAN   Rsvg-2.0.gir
/home/fiona/br-test-pkg/bootlin-x86-64-musl/host/opt/ext-toolchain/bin/../lib/gcc/x86_64-buildroot-linux-musl/14.3.0/../../../../x86_64-buildroot-linux-musl/bin/ld: 
./.libs/librsvg-2.so: undefined reference to `open64'
collect2: error: ld returned 1 exit status

Best regards,
Fiona
