[PATCH] Remove nios2-linux-gnu

[Florian Weimer]

* Adhemerval Zanella:

> 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 propoer compiler there
> is no much sense in keep it on glibc.

Typo: prop[]er

Rest looks okay to me.
