Hi,

the conf utility hangs on several architectures such as sparc64 during build [1][2][3]:

Attaching strace shows the same string written over and over again:

The problem seems to be that CONFIG_EROFS_FS_ZIP_LZMA_DEFAULT_MAX_STREAMS cannot be set
with the "yes" command. Instead, it needs to be defined in debian/config/config.

Testing this now.

I can confirm that adding CONFIG_EROFS_FS_ZIP_LZMA_DEFAULT_MAX_STREAMS=16 to debian/config/config
fixes the problem and the kernel package can be built normally on sparc64. I assume that the same
fix would also work on alpha and sh4.

Thanks,
Adrian
