[Ohrrpgce] SVN: james/12141 Docker: add a first-draft attempt at an mxe build environment in a docke

[Ralph Versteegen]

Oh, sorry, I did write up instructions for compiling but didn't send them
yet.

In order to compile a fbc that can target android you of course need to use
https://github.com/rversteegen/fbc.git which I have just merged upstream
master into (and which therefore support emscripten too!) However this
branch doesn't have the mac branch merged into it. That doesn't matter
until we have a cross-compiler that targets Mac. At that point I can merge
them. (Please ignore my androidmac branch, it's very old and I can't even
remember what's going on in it.

Anyway, to target android it isn't necessary to build the rtlib or gfxlib2
for it, unlike other platforms, due to our hacky android build system.

#!/bin/sh

cat <<EOF > config.mk
prefix=$HOME/local/fbc-git
CFLAGS += -Wfatal-errors -g
#FBC := ~/local/fbc-1.05/bin/fbc

# For some reason mxe puts ffi.h in a separate include dir, so it can't be
found.
# libffi is only needed for FB's ThreadCall operator, which we don't use,
so just disable it.
CFLAGS += -DDISABLE_FFI

EOF
