When building util-linux with libuuid enabled on noMMU targets
(e.g., bootlin-armv7m-uclibc or bootlin-m68k-5208-uclibc), the build
fails with the following error:
libuuid/src/gen_uuid.c: In function ‘uuid_generate_time_generic’:
libuuid/src/gen_uuid.c:629:17: error: implicit declaration of function ‘pthread_atfork’; did you mean ‘pthread_join’? [-Wimplicit-function-declaration]
629 | pthread_atfork(NULL, NULL, reset_uuidd_cache);
| ^~~~~~~~~~~~~~
| pthread_join
This happens because pthread_atfork() is not available on noMMU
configurations as reported by commit 59fe7547a495 ("package/libcap-ng:
disable pthread support on nommu").
Fix this by adding a dependency on BR2_USE_MMU to libuuid. As a
consequence, also propagate the BR2_USE_MMU dependency to all packages
selecting BR2_PACKAGE_UTIL_LINUX_LIBUUID to prevent "unmet direct
dependencies" Kconfig errors.

Changes v3 -> v4:
- Add dependency on BR2_USE_MMU for libuuid
- Update version to 1.9.13.
- Add hash file for drogon-v1.9.13-git4.tar.gz and LICENSE.
- Drop patches already merged in version v1.9.13
- Fix typo EXMPLES -> EXAMPLES
- Fix building failure on SPARC/SPARC64
Changes v2 -> v3:
- The PRs related to the patches have all been merged. The first PR was
merged by combining the three patches into a single one. Replace all
Upstream: links with the link to the final commit.
- Add help text to the added KConfig options.
- Select external libraries for BROTLI and YAML_CONFIG options.
- Drop the host configurations. Files too.
- Always add -DBUILD_CTL=ON to HOST_DROGON_CONF_OPTS (together with
-DBUILD_TESTS=OFF and -DBUILD_EXAMPLES=OFF).
Changes v1 -> v2:
- Drop BR2_ARCH_IS_64 dependency. It has been tested on imx6ull platform.
- Add DROGON_INSTALL_STAGING
- Add 0004-Fix-building-error-for-Werror-unused-value.patch for trantor
submodule.

+Subject: [PATCH] Fix EPOLLRDHUP/POLLRDHUP mismatch on Linux SPARC/SPARC64
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Fix a build failure reported by Buildroot autobuild for the
+bootlin-sparc64-glibc configuration:
+
+ EpollPoller.cc:41:26: error: static assertion failed:
+ EPOLLRDHUP != POLLRDHUP
+
+On SPARC/SPARC64, EPOLLRDHUP (0x2000) and POLLRDHUP (0x0800) are
+different bits, breaking the assumption elsewhere in this file that
+epoll and poll flags are interchangeable.
+
+Introduce a combined RDHUP value for this architecture and translate
+it before epoll_ctl() and after epoll_wait(), since revents_ is later
+tested against POLLRDHUP in Channel::handleEvent() — otherwise
+half-close detection would silently break at runtime.
+
+This patch is inspired by the equivalent fix in lighttpd:
+https://redmine.lighttpd.net/issues/3251
