If you're on 64bit OS and want to compile musl and sqlite, run this (Ubuntu 64bit)

musl-1.2.0.tar.gz (sig) - February 20, 2020

This release moves all 32-bit archs to 64-bit time_t, enabling them to represent times beyond January of 2038.

There are no new requirements on kernel version, and this is not a hard ABI break, but the type changes do impact compatibility between code built against previous versions of musl and code built against musl 1.2. Users upgrading 32-bit systems should read the detailed time64 release notes. 64-bit systems are not affected.

If compile on Ubuntu 64bit, you may change to:

CROSS_COMPILE="/usr/bin/"
