On FreeBSD, ZSTD_ASM_SUPPORTED is defined as 0, but on macOS and Linux it is defined as 1, yet we don't build any of the assembly sources. Rather than add them just for bootstrapping on non-FreeBSD, explicitly define ZSTD_DISABLE_ASM so they're not needed and everything is consistent. This fixes building a bootstrap LLVM toolchain on non-FreeBSD amd64 (the only architecture with assembly available). Reviewed by: emaste, imp Differential Revision: https://reviews.freebsd.org/D41543
