Build for musl archs

Hello there,

I'm trying to package wtype for VoidLinux but I'm stuck on musl builds.

It seems that reallocarray is the source of the issue here.

Am I missing something ?

Thanks a lot !

Right --- reallocarray is not available in musl. Switched to plain realloc. Seems to build in musl Void now.
