a570eaabcd 6l: 
use libbio instead of maintaining own buffer

libbio:
	always use vlong offsets; die if off_t is too small

6c72bfa55b fix bug in stack overflow check. 
if stack is in low memory and frame size is huge, test could wrap around!
fix by omitting test altogether if we know frame is big.

34514bdb72 Use a single Make.conf for setting CC, etc. 
This makes it easy to build with other flags
(like -ggdb) or other compilers (like cc64).

9aad9fef76 make 6a, 6c, 6g, 6l, libmach_amd64 build on 64-bit gcc. 
these guys really really want long to be 32-bits,
so ,s/long/int32/ (and then manual fixup).
still passes all tests.

(i started out looking for just those longs that
needed to be int32 instead, and it was just too hard
to track them down one by one.)

the longs were rare enough that i don't think
it will cause integration problems.
