I'll note that ampere2's main-armv7 p94c4ac6b071b_sc87b3f0006
build processing stopped updating its status while the last
builder was still running:

http://ampere2.nyi.freebsd.org/build.html?mastername=main-armv7-default&build=p94c4ac6b071b_sc87b3f0006

shows libretro-mame-20220124_1 but no updates after its
Elapsed 13:29:45 update. Eventually main-arm64 starting
building:

http://ampere2.nyi.freebsd.org/build.html?mastername=main-arm64-default&build=p711a2f7f1ca4_s0d965bc0342


So main-armv7 has not completed a build since the one that
started at Thu, 03 Oct 2024 04:21:42 GMT and took 61:50:05
to build. That predates the libmd.so <http://libmd.so/>.6 -> libmd.so <http://libmd.so/>.7
change in main if I remember right. Once main-armv7 does
build, it will have jumped to be based on LLVM 19 as well.

I've no clue what happend on ampere2 to stop the main-armv7
build from completing.
