produce statically linked binary

[dafanasiev]

with this patch and using cargo build --release --target x86_64-unknown-linux-musl --features bin_core,ls_filesystem,vendored you can make statically linked binary (now binary depends on glibc 2.32 and cant run on centos7 (and some other distrs))

Hi. Thanks for the issue and the patch, I will apply it in the next release. But why is it an issue (not a PR)?
