Hello, I tested big-endian binaries by sh4(eb)-linux-user with a small patch(attached) for building sh4eb-linux-user. But I don't understand that this patch is needed or not.
sh4eb-linux-user is OK using static link binaries. But I feel that sh4eb-linux-users has some problem(?) using dynamic link binaries. 1) If host-os has /etc/ld.so.cache, sh4eb-linux-users is NG.
