fixed link issues on aarch64 musl

andreeaflorescu · Samuel Ortiz · commit 83c98b272433 · 2019-04-09T00:14:27.000+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.
