firefox and rust build failure

[mlh%goathill.org@localhost (MLH)]

Been trying for the past two weeks to build anything using rust
and updating pkgsrc every time. rustc always fails to execute.

rust-bin-1.44.0     Safe, concurrent, practical language (official binaries)

error: process didn't exit successfully: `rustc -vV` (exit code: 2)
--- stderr
/bin/sh: Cannot execute ELF binary /usr/pkgnew/bin/rustc

*** Error code 101

Stop.
make[3]: stopped in /usr/pkgsrc/devel/cbindgen
