>Description:
libffi (which is needed by python) cannot be built. The code assumes Linux and 
makes a syscall to flush the cache. I'm not sure how to replace that on NetBSD:

libtool: compile:  cc -DHAVE_CONFIG_H -I. -I./include -Iinclude -I./src -Wall 
-g -fexceptions -O2 -MT src/m68k/ffi.lo -MD -MP -MF src/m68k/.deps/ffi.Tpo -c 
src/m68k/ffi.c  -fPIC -DPIC -o src/m68k/.libs/ffi.o
src/m68k/ffi.c:13:26: error: asm/cachectl.h: No such file or directory
src/m68k/ffi.c: In function 'ffi_prep_closure_loc':
src/m68k/ffi.c:269: error: 'SYS_cacheflush' undeclared (first use in this 
function)
src/m68k/ffi.c:269: error: (Each undeclared identifier is reported only once
src/m68k/ffi.c:269: error: for each function it appears in.)
src/m68k/ffi.c:269: error: 'FLUSH_SCOPE_LINE' undeclared (first use in this 
function)
src/m68k/ffi.c:270: error: 'FLUSH_CACHE_BOTH' undeclared (first use in this 
function)
*** Error code 1

Stop.

>How-To-Repeat:
try to buid libffi on mac68k
