[OE-core] [PATCH] mesa: Disable asm on musl

[Paul Eggleton]

Can we have bit more detail in the commit message about what the issues are? 
We're not supposed to rely solely on a bug report reference to do that; also 
if it's considered a workaround and we're working with upstream to fix it, the 
commit message should state that as well.

Thanks
Paul
