The only mention of m16 in the config.log is where it says:

clang -m64 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE
-Wstrict-prototypes -Wredundant-decls -Wall -Wundef -Wwrite-strings
-Wmissing-prototypes -fno-strict-aliasing -fno-common
-fsanitize=undefined -Werror -Wno-string-plus-int
-Wno-initializer-overrides -Wendif-labels -Wmissing-include-dirs
-Wempty-body -Wnested-externs -Wformat-security -Wformat-y2k
-Winit-self -Wignored-qualifiers -Wold-style-definition -Wtype-limits
-fstack-protector-all -m16 -o config-temp/qemu-conf.exe
config-temp/qemu-conf.c -m64 -g
clang: error: unknown argument: '-m16'
