Nightly built Linux binaries are dependent on glibc

Although glibc is quite common on Linux distros, nowadays there are getting more [musl][]-based distros (e.g., [Alpine Linux][]) due to containers (e.g., Docker).  As unlike glibc musl is intended to be statically linked, we can make Linux binaries more portable by static link to musl instead of depending on glibc.
