fix link issues on aarch64 musl

andreeaflorescu · bonzini · commit f651ed9c8d10 · 2019-06-04T14:26:13.000+02:00
The linker was unable to find __addtf3, __multf3 and __subtf3. Added target-feature=+crt-static and link-arg=-lgcc as a temporary workaround. This seems to be the accepted fix in the Rust community: rust-lang/compiler-builtins#201 A permanent fix is yet to be implemented in the Rust compiler.
