Hi,
I'm trying to build libluajit.a for an iOS device build, but I keep
getting a non-ARM library. When linking against it, I get:
ld: warning: ignoring file /Users/sgraham/luajit-2.0/src/libluajit.a,
file was built for archive which is not the architecture being linked
(armv7)
I tried to follow doc/install.html updated for 5.1 instead of 4.3, but
I'm not sure what I've done wrong. I tried both b10 and git HEAD.
Below are the only changes from git HEAD. Without -m32, buildvm
complained that there was a pointer size mismatch.

And, building with the following script:

make clean

I tried both clang and gcc also.
I'm sure there's something obvious I'm doing wrong here... if anyone
could point it out I would be grateful!
Thanks,
scott
