Enable big-endian suffixed dynamic linker per glibc multi-abi support.
And to avoid a future churn and version pairingi hassles, also allow
arc700 although glibc for ARC currently doesn't support it.

Is this one eligible for being back-ported to older GCCs?
At least GCC 9.x would be really good.

Well its a hard requirement considering glibc is still using gcc-9 !
Thx,

FWIW this change needs a pairing glibc change so must NOT be included for upcoming
2020.x release which still has old version of glibc !

For glibc needs can this be backported to gcc-9 please !
