Bernd Kuhls 9843276c79 package/mjpg-streamer: fix build with gcc >= 14
When mjpg-streamer is built with gcc >= 14 using libjpeg (rather than
jpeg-turbo), and with SDL is enabled (to enable the output_viewer),
the compilation can fail with error:

    output_viewer.c:125:32: error: assignment to ‘boolean (*)(struct jpeg_decompress_struct *)’ from incompatible pointer type ‘int (*)(struct jpeg_decompress_struct *)’ [-Wincompatible-pointer-types]

The issue can be reproduced with the commands:

    cat >.config <<EOF
    BR2_aarch64=y
    BR2_TOOLCHAIN_EXTERNAL=y
    BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
    BR2_PACKAGE_LIBJPEG=y
    BR2_PACKAGE_MJPG_STREAMER=y
    BR2_PACKAGE_SDL=y
    EOF
    make olddefconfig
    make mjpg-streamer

This commit adds a patch to fix this issue.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on OFTC IRC.
