Failed to install on armv7l

[Shulyaka]

Hi I am having the below error while installing on armv7l (alpine). It looks like the project builds its own libc which in turn uses a shorter length of time_t. Is there a way to link it against the system libc?

Fixed by updating time_t to i64 in libc-0.2.155/src/unix/linux_like/linux/musl/mod.rs, more info here: rust-lang/libc#1848
