Is dump-markdown (and the associated tests) broken?

[kbara]

Looking at #251, I tried to manually run dump-markdown. doc/Makefile contains a lot of lines like ../tools/dump-markdown "proto 47" > $@.tmp && mv $@.tmp $@. However, when I try to invoke ../tools/dump-markdown, it fails:

% ../tools/dump-markdown "l1"

I have dasm.lua, in pflua/deps/dynasm, but it's not in the search path, as far as I can see.

I can reproduce this on an entirely clean checkout of pflua.

WFM on a fresh checkout. I think it works because of this in common.mk:

export LUA_PATH := $(ABS_TOP_SRCDIR)/deps/dynasm/?.lua;;
export LD_LIBRARY_PATH := $(ABS_TOP_SRCDIR)/deps/dynasm:$(LD_LIBARARY_PATH)

You don't see this on the command line as it's just an environment flag.
