package/glibc: only supports ARC little-endian since glibc 2.41

Browse Source 
Since upstream commit
https://sourceware.org/git/?p=glibc.git;a=commit;h=4ff55d08df0e6f11cbd217f4dca4532bd7d9330d,
glibc no longer supports ARC big-endian, and the configure step fails
with:

checking for egrep -e... (cached) /bin/grep -E
checking for big endian... yes
configure: error: big-endian not supported
make: *** [package/pkg-generic.mk:263: /home/buildroot/instance-0/output-1/build/glibc-2.41-70-g1502c248d58cb99a203731707987a4342926e830/.stamp_configured] Error 1

This commit was first merged in glibc 2.41, so this issue is
applicable to both master (glibc 2.42) and 2025.02.x (glibc 2.41).
