Arch Linux

Description:

Cannot compile firefox package as it is in the repositories. It starts to
work after downgrading to rust 1.47. Another way to work around the issue
seems to be commenting out --enable-rust-simd in the mozconfig. I assume
that has runtime performance implication. I do not know enough about rust
to be able to debug this further.

Additional info:
* package version(s)
current firefox, 83.0
rust 1.48
* config and/or log files etc.
