Building rsync with --enable-md5-asm, --enable-roll-simd, or
--enable-roll-asm fails on FreeBSD/amd64.
ld.lld: error: undefined symbol: md5_process_asm
ld.lld: error: undefined symbol: get_checksum1
The configure script accepts both "x86_64" and "amd64" as valid CPU
architectures for this purpose, and substitutes the name into the
Makefile ...
OBJS3=progress.o pipe.o $(MD5_ASM_amd64) $(ROLL_SIMD_amd64) $(ROLL_ASM_amd64)
... but only the *_x86_64 variables are defined in Makefile.in:
ROLL_SIMD_x86_64=simd-checksum-x86_64.o
ROLL_ASM_x86_64=simd-checksum-avx2.o
MD5_ASM_x86_64=lib/md5-asm-x86_64.o
This can be fixed any number of ways; the following diff is just an
example:
