lang/python38 fails on NetBSD 8 and NetBSD 9 on sparc64, powerpc, alpha, 
aarch64, mips64eb and possibly others with:

build/temp.netbsd-8.1_STABLE-sparc64-3.8/usr/pkgsrc/lang/python38/work/Python-3.8.0/Modules/_ctypes/callproc.o: 
In function `_ctypes_callproc':
callproc.c:(.text+0x1a80): warning: Warning: reference to the libc supplied alloca(3); 
this most likely will not work. Please use the compiler provided version of alloca(3), 
by supplying the appropriate compiler flags (e.g. not -std=c89).
