No. See my posts in the other part of this thread where threading was
once broken by a stupid mobile phone MUA.

Every "native" setting is just resolved by gcc at compile time to some
concrete setting like "core2". There is nothing magical about it and you
also don't need to recompile glibc or gcc any more than you need after
switching your march settings between two other settings.

No one had any breakage during the time when -march=core2 was introduced
and all Core2 owners switched from -march=nocona to -march=core2. There
should be no more breakage when switching to "native".

Correlation does not imply causation.
