Remove nios2-linux-gnu

GCC 15 (e876acab6cdd84bb2b32c98fc69fb0ba29c81153) and binutils
(e7a16d9fd65098045ef5959bf98d990f12314111) both removed all Nios II
support, and the architecture has been EOL'ed by the vendor.  The
kernel still has support, but without a proper compiler there
is no much sense in keep it on glibc.
