lmdb testcases fail when running in a qemu linux-user environment.
The reason is, that qemu can technically not support emulating
robust mutexes, and as such the
pthread_mutexattr_setpshared(&mattr, PTHREAD_PROCESS_SHARED)
call in mdb.c will fail.
By default lmdb will enable MDB_USE_POSIX_MUTEX on Linux.
Now, if lmdb would detect at runtime if the pthread() call is supported
and fall back to the MDB_USE_POSIX_SEM implementation, then
lmdb would fully work on qemu-user as well.
Is that an option?
Has something like this been discussed upstream maybe?

PS: I'm willing to come up with a patch if needed.
