    build: fix build on Solaris 10 with GCC 8.4
    
    munmap on Solaris 10, depending on compile time defines can use caddr_t
    instead of void* as its argument failing the build with the following
    error message:
    
    error: passing argument 1 of 'munmap' from incompatible pointer type
    
    cast to void*, should be safe.
